Marin County is one of the original 27 counties of California, created February 18, 1850, following adoption of the California Constitution of 1849 and just months before the state was admitted to the Union. 
According to General Mariano Vallejo, who headed an 1850 committee to name California's counties, the county was named for "Marin", great chief of the tribe Licatiut". Marin had been named Huicmuse until he was baptized as "Marino" at about age 20. Marin / Marino was born into the Huimen people, a Coast Miwok tribe of Native Americans who inhabited the San Rafael area. Vallejo believed that "Chief Marin" had waged several fierce battles against the Spanish. Marino definitely did reside at Mission Dolores (in modern San Francisco) much of the time from his 1801 baptism and marriage until 1817, frequently serving as a baptism witness and godfather; he may have escaped and been recaptured at some point during that time. Starting in 1817, he served as an alcalde (in effect, an overseer) at the San Rafael Mission, where he lived from 1817 off and on until his death. In 1821, Marino served as an expedition guide for the Spanish for a couple of years before escaping and hiding out for some months in the tiny Marin Islands (also named after him); his recapture resulted in a yearlong incarceration at the Presidio before his return to the Mission San Rafael area for about 15 years until his death in 1839.  In 2009, a plaque commemorating Chief Marin was placed in Mill Valley.
Another version of the origin of the county name is that the bay between San Pedro Point and San Quentin Point was named Bahía de Nuestra Señora del Rosario la Marinera in 1775, and that Marin is simply an abbreviation of this name. 
The Coast Miwok Indians were hunters and gatherers whose ancestors had occupied the area for thousands of years. About 600 village sites have been identified in the county. The Coast Miwok numbered in the thousands. Today, there are few left and even fewer with any knowledge of their Coast Miwok lineage. Efforts are being made so that they are not forgotten. 
Francis Drake and the crew of the Golden Hind was thought to have landed on the Marin coast in 1579 claiming the land as Nova Albion. A bronze plaque inscribed with Drake's claim to the new lands, fitting the description in Drake's own account, was discovered in 1933. This so-called Drake's Plate of Brass was revealed as a hoax in 2003. 
In 1595, Sebastian Cermeno lost his ship, the San Agustin, while exploring the Marin Coast. The Spanish explorer Vizcaíno landed about twenty years after Drake in what is now called Drakes Bay. However the first Spanish settlement in Marin was not established until 1817 when Mission San Rafael Arcángel was founded partly in response to the Russian-built Fort Ross to the north in what is now Sonoma County.[ citation needed] Mission San Rafael Arcángel was founded in what is now downtown San Rafael as the 20th Spanish mission in the colonial Mexican province of Alta California by four priests, Father Narciso Duran from Mission San Jose, Father Abella from Mission San Francisco de Asís, Father Gil y Taboada and Father Mariano Payeras, the President of the Missions, on December 14, 1817, four years before Mexico gained independence from Spain.[ citation needed]
According to the U.S. Census Bureau, the county has a total area of 828 square miles (2,140 km2), of which 520 square miles (1,300 km2) is land and 308 square miles (800 km2) (37.2%) is water.  It is the fourth-smallest county in California by land area. According to the records at the County Assessor-Recorder's Office, as of June 2006, Marin had 91,065 acres (369 km2) of taxable land, consisting of 79,086 parcels with a total tax basis of $39.8 billion. These parcels are divided into the following classifications:
|Parcel Type||Tax ID||Quantity||Value|
|Single Family Residential||11||61,264||$30.13 billion|
|Mobile Home||12||210||$7.62 million|
|House Boat||13||379||$61.83 million|
|Multi Family Residential||14||1,316||$3,973.51 million|
|Industrial Unimproved||40||113||$12.24 million|

|Commercial Unimproved||50||431||$97.89 million|
|Commercial Improved||51||7,911||$4.52 billion|
Geographically, the county forms a large, southward-facing peninsula, with the Pacific Ocean to the west, San Pablo Bay, and San Francisco Bay to the east, and – across the Golden Gate – the city of San Francisco to the south. Marin County's northern border is with Sonoma County.
Most of the county's population resides on the eastern side, with a string of communities running along San Francisco Bay, from Sausalito to Tiburon to Corte Madera to San Rafael. The interior contains large areas of agricultural and open space; West Marin, through which State Route 1 runs alongside the California coast, contains many small unincorporated communities whose economies depend on agriculture and tourism. West Marin has beaches which are popular destinations for surfers and tourists year-round.
Notable features of the shoreline along the San Francisco Bay include the Sausalito shoreline, Richardson Bay, the Tiburon Peninsula, Ring Mountain, and Triangle Marsh at Corte Madera. Further north lies San Quentin State Prison along the San Rafael shoreline.

Marin County is considered in the California Floristic Province, a zone of extremely high biodiversity and endemism. There are numerous ecosystems present, including Coastal Strand, oak woodland, mixed evergreen forest, and Coast Redwood Forests chaparral and riparian zones. There are also a considerable number of protected plant and animal species present: Fauna include the California red-legged frog (Rana aurora draytonii) and California freshwater shrimp while flora include Marin Dwarf Flax, Hesperolinon congestum; Tiburon Jewelflower, Streptanthus niger; and Tiburon Indian paintbrush, Castilleja neglecta.
Notably, the Lagunitas Creek Watershed is home to the largest remaining wild run of Coho salmon (Oncorhynchus kisutch) in Central California. These coho are part of the "Central California Coast Evolutionarily Significant Unit, " or CCC ESU, and are listed as "endangered" at both the state and federal level.
Significant efforts to protect and restore these fish  have been underway in the Watershed since the 1980s. Fifty percent of historical salmon habitat is now behind dams. Strong efforts are also being made to protect and restore undammed, headwater reaches of this Watershed in the San Geronimo Valley, where upwards of 40% of the Lagunitas salmon spawn each year and where as much as 1/3 of the juvenile salmon (or fry) spend their entire freshwater lives. The "Salmon Protection and Watershed Network"  leads winter tours for the public to learn about and view these spawning salmon, and also leads year-round opportunities for the public to get involved in stream restoration, monitoring spawning and smolt outmigration, juvenile fish rescue and relocation in the summer, and advocacy and policy development. Around 490 different species of birds have been observed in Marin County. 
Despite the lack of rain in the Marin County area due to historic drought levels,  in 2014, an estimated 20,000 juvenile Coho salmon made the migration from their spawning grounds in the Lagunitas Creek area to the Pacific Ocean. This increase in migration was significantly up from the previous historic record for the same migration measured in 2006 at 11,000. 
In 2010, all of the county's beaches were listed as the cleanest in the state.

For most of the 20th century, Marin County was a Republican stronghold in presidential elections. From 1892 until 1984, the only Democrats to win there were Franklin Roosevelt and Lyndon Johnson. However, the brand of Republicanism prevailing in Marin County was historically a moderate one. Like most of the historically Republican suburbs of the Bay Area, it became friendlier to Democrats as the demographics of the area changed and the national party embraced social and religious conservatism. In 1984, it very narrowly voted for Walter Mondale and has supported the Democratic candidate in every presidential election since then. Since the 1990s, it has become one of the Democrats' major strongholds in both California and the nation. Out of California counties, only San Francisco County and Alameda County voted more Democratic in the 2008 Presidential election.
On November 4, 2008, the citizens of Marin County voted strongly against Proposition 8, a constitutional amendment which eliminated the right of same-sex couples to marry, by a 75.1 percent to 24.9 percent margin. The official tally was 103,341 against and 34,324 in favor.  Only San Francisco County voted against the measure by a wider margin (75.2% against). 
According to the California Secretary of State, as of February 10, 2019, Marin County has 161,870 registered voters. Of those, 89,526 (55.31%) are registered Democrats, 23,380 (14.44%) are registered Republicans, 7,020 (4.35%) are registered with other political parties, and 41,908 (25.89%) have declined to state a political party.  Democrats hold wide voter-registration majorities in all political subdivisions in Marin County. Democrats' largest registration advantage in Marin is in the town of Fairfax, wherein there are only 344 Republicans (6.1%) out of 5,678 total voters compared to 3,758 Democrats (66.2%) and 1,276 voters who have declined to state a political party (22.5%).
The last time Marin elected a Republican to represent them in the United States House of Representatives was William S. Mailliard in 1972. The last competitive race for the U.S. House of Representatives in Marin was in 1982 when Barbara Boxer was first elected. The longest serving representative of Marin in congress was Clarence F. Lea who served in the House from 1917 to 1949.[ citation needed]
Due to the rapidly expanding nature of California's population, Marin's congressional district has changed numerous times over the decades. The county has been part of the 2nd congressional district of California since 2012; the only other time it was part of the 2nd district was 1902–12. It has also been part of the 1st (1894–1902 and 1912–66), 3rd (1864–94), 5th (1974–82), and the 6th (1972–74 and 1982–2012). The only time the county has not been in a single congressional district was between 1966 and 1972, when it was divided between the northern half in the 1st district and the southern half in the 6th district.[ citation needed]
In 2002, former U.S. President George H.W. Bush denounced convicted American Taliban associate John Walker Lindh as "some misguided Marin County hot-tubber," as a reference to the county's liberal, " hippie" political culture, mispronouncing "Marin" as he did so. Outraged by the label, some local residents wrote scathing letters to the Marin Independent Journal, complaining of Bush's remarks. In response, Bush wrote a letter to readers in the same newspaper, admitting regret and promising to not use the phrases Marin County and hot tub "in the same sentence again."
