Boulder County was one of the original 17 counties created by the Territory of Colorado on November 1, 1861. The county was named for Boulder City and Boulder Creek, so named because of the abundance of boulders in the area. Boulder County retains essentially the same borders as in 1861, although a 27.5 square miles (71.2 km2) of its southeastern corner and its approximate population of 40,000 became part of the City and County of Broomfield in 2001.

Boulder County is divided into three districts each represented by a commissioner elected county-wide. The three commissioners comprise the county Board of Commissioners and represent the county as a whole. Each commissioner must reside in their respective district and may be elected to a maximum of two four-year terms.
The Board of County Commissioners are full-time public servants and approve the budget for the entire County government. The Board also oversees the management of 10 County departments and the daily operations of the county, work that is done by a county manager or a chief administrative officer in some counties.
Boulder County has seven other county-wide elected officials, including the District Attorney, who represents the 20th Judicial District.

As of June 2013[update], Boulder County is regarded[by whom?] as one of the most liberal counties in Colorado. Republicans took less than 28% of the vote in Boulder County in both 2008 and 2012 and took only 22% in 2016.
In 2000, Green Party presidential candidate Ralph Nader took 11.82% of the vote in Boulder County, more than twice the 5.25% he took statewide in Colorado, and more than four times his 2.73% nationwide vote share.
Boulder County has also demonstrated its liberal leanings in referenda on social issues, such as in 2006, when nearly 2/3 of Boulder County voters voted to reject Amendment 43, a constitutional amendment defining marriage as between one man and one woman. Although the amendment passed statewide with 55% of the vote, only 33% of Boulder County supported it. In 2012, over 66% of Boulder County voted in favor of Amendment 64, legalizing marijuana in the state of Colorado.
The 20th Judicial District of Colorado, the state trial court of general jurisdiction, serves and is coextensive with Boulder County. As of 2009 the 20th Judicial Circuit has eight District Court judges. The Boulder County Court, the state trial court of limited jurisdiction, consists of five judges and six magistrates.
Boulder County has two combined courthouses:
- The Boulder County Justice Center is located in the City of Boulder and is headquarters to the 20th Judicial District of Colorado. The office of the district attorney is also here, as is the Juvenile Assessment Center, the county's combined assessment and detention facility.
- The Longmont Courthouse in the City of Longmont acts as an extension of the County Court and the District Attorney's Office.
