Humboldt County is a county in the U.S. state of Iowa. As of the 2010 census, the population was 9,815.  The county seat is Dakota City.  The county was created in 1857 and named in honor of Alexander von Humboldt.
Iowa's entry to the union was approved by Congress on March 3, 1845, with statehood beginning on December 28, 1846, following approval of the state's constitution and boundaries. In order to establish county government across the state, the Iowa General Assembly passed an act on January 15, 1851 which created fifty counties in the half of the state where county government had not yet been established. Humboldt County was created by this act, containing its present area, as well as four townships in present-day Webster County: Jackson, Deer Creek, Badger, and Newark.  It was named after Alexander von Humboldt.  On January 21, 1855, an act merged the northern half of Humboldt County and Bancroft County into Kossuth County, with the southern half of Humboldt County merging into Webster County. 
The Sixth General Assembly passed another act, reestablishing Humboldt County. The act was passed on January 28, 1857 and went into effect on February 26.  However, an error omitted the lower four townships (Jackson, Deer Creek, Badger, and Newark) from returning to Humboldt County. The error was not caught until the next session of the general assembly, and the general assembly passed a bill redefining Humboldt County to include the four townships on March 11, 1858.  However, in the interceding time, the Constitution of Iowa came into effect, including the provision that "future laws altering county boundaries should be submitted to a vote of the people of the counties concerned and must be approved by them before going into effect".  In a court case originating in the disputed area, the Iowa Supreme Court was asked to decide which county court had original jurisdiction. In their clarification, they ruled the March 11, 1858 clarification of Humboldt County's boundaries unconstitutional, as it had not been submitted to a public vote in the counties involved. In his decision, Chief Justice Ralph P. Lowe wrote, "We are compelled to conclude that township 90, in ranges 27 to 30, west of the 5th principal meridian, is still in and forms a part of Webster county. Of course we can pay no attention to conjectural surmises and vague suspicions, which have been made and entertained in relation to some unfairness which may have been practiced in the final passage of the act of 1857, creating the county of Humboldt. If such was the case, no evidence of the fact has been presented to us."  The "vague suspicions" include a rumor that John Duncombe of Fort Dodge (namesake of Duncombe, Iowa and plaintiff in the lawsuit) had tricked Humboldt County into cedeing the southern four townships to Webster County "on loan", or was otherwise responsible for the "error". 
Unlike all counties to its east and west, Humboldt County has only 12 townships. Although founded with the standard 16 townships in January 15, 1851, the county was removed from existence in 1855. 
While Humboldt County does not have any state parks, it has county parks. South of Humboldt is Frank A. Gotch County Park. It is named for Frank Gotch, a world-champion, undefeated wrestler from Humboldt. The park is near his childhood farm and is also home to the confluence of the East and West Forks of the Des Moines River. The park features campgrounds and a well-known converted railroad bridge used by the Minneapolis and St. Louis Railway. The bridge is part of the Three Rivers Trail, a converted rail route that runs from Eagle Grove west to Rolfe.
Near Bradgate is the Willow Access Area. The terrain is very wooded. In south Rutland is Rose Mill Park. The area can be used for camping and also has access to the Rutland Dam and West Fork of the Des Moines River. The dam is being restored, and most of the park is new. The river is known for its forested limestone bluffs and grassy banks.
Further downriver near Humboldt is Oxbow Park, which contains boating access ramps and lots of scenic open space. The park's southern border is Iowa Highway 3, and south of that is Joe Sheldon County Park. The park is split into two sections, one mostly for camping and one focused on recreation. There is access to the West Fork of the Des Moines River from the lower part of the park.
Continuing along the river, the Lake Nokomis area begins, popular for its woods and small ponds. The Cottonwood Trail also runs through the area.
West of Livermore, Lott's Park allows access to Lott's Creek. The park has lots of benches and picnic tables. South of Ottosen is the Ottosen Marsh State Game Management Area, colloquially the Ottosen Potholes. East of Dakota City is the Dakota City River Park, near an old dam and the Humboldt County Historical Museum. Near the unincorporated community of Pioneer is the Pioneer Prairie Pothole Wildlife Area.
