Hannibal is a city in Marion and Ralls counties in the U.S. state of Missouri. Interstate 72 and U.S. Routes 24, 36, and 61 intersect in the city, which is located along the Mississippi River, approximately 100 miles (160 km) northwest of St. Louis and approximately 100 miles (160 km) west of Springfield, Illinois. According to the 2010 U.S. Census, the population was 17,606, making it the largest city in Marion County. The bulk of the city is in Marion County, with a tiny sliver in the south extending into Ralls County.
Hannibal is not the county seat, but it has one of two county courthouses. There is also one in Palmyra, the county seat, which is located more in the center of the county. This is the principal city of the Hannibal, Missouri micropolitan area, which consists of both Marion and Ralls counties.
The site of Hannibal was long occupied by various cultures of indigenous Native American tribes.
The river community is best known as the 19th-century boyhood home of author Samuel Langhorne Clemens (aka Mark Twain). The settings of Twain's novels The Adventures of Tom Sawyer and Adventures of Huckleberry Finn are inspired by this town. Numerous historical sites are associated with Mark Twain and places depicted in his fiction.
Hannibal draws both American and international tourists. The Mark Twain Boyhood Home & Museum marked its 100th anniversary in 2012 and has had visitors from all 50 states and some 60 countries.  Most Hannibal residents enjoy the visitors, and the town at large benefits from tourism revenue. 
After the Louisiana Territory was acquired by the United States in 1803, European-American settlers began to enter the area. The town was laid out in 1819 by Moses Bates  and named after Hannibal Creek (now known as Bear Creek).  The name is ultimately derived from the hero of ancient Carthage in actual Tunisia, Hannibal.  Although the city initially grew slowly, with a population of 30 by 1830, its access to the Mississippi River and railroad transportation fueled growth to 2,020 by 1850. It annexed the town of South Hannibal in 1843.  Hannibal gained "city" status by 1845. 
Hannibal was Missouri's third-largest city when the Hannibal and St. Joseph Railroad was organized in 1846 by John M. Clemens (Mark Twain's father) and associates.  It was built to connect to St. Joseph, Missouri in the west, then the state's second-largest city. This railroad was the westernmost line before the Transcontinental Railroad was constructed. It transported mail for delivery to the first outpost of the Pony Express.
The city has since served as a regional marketing center for livestock and grain as well as other products produced locally, such as cement and shoes.  Cement for the Empire State Building and Panama Canal was manufactured at the Atlas Portland Cement Company in the nearby unincorporated company town of Ilasco. 
The Mark Twain Memorial Lighthouse was constructed in 1933 as a public works project under President Franklin D. Roosevelt. It has been lit on ceremonial occasions at three separate times by Presidents Roosevelt, John F. Kennedy, and Bill Clinton. Rockcliffe Mansion, a private house on a knoll in Hannibal, is listed on the National Register of Historic Places.
In 2011, the Mark Twain Boyhood Home and Museum released Mark Twain: Words & Music, a CD featuring entertainers who recount Mark Twain's life in spoken word and song. Several songs were written especially for the project and refer to Hannibal, including "Huck Finn Blues" by Brad Paisley and "Run Mississippi" by Rhonda Vincent. Other artists include Jimmy Buffett as Huckleberry Finn, Clint Eastwood as Twain, and Garrison Keillor as the narrator of the project.  
Hannibal is next to the Mississippi River and borders East Hannibal, Illinois. According to the United States Census Bureau, the city has a total area of 16.21 square miles (41.98 km2), of which 15.74 square miles (40.77 km2) is land and 0.47 square miles (1.22 km2) is water.
