Atchison County is the northwesternmost county in the U.S. state of Missouri. As of the 2020 census, the county had a population of 5,305.^[1] Its county seat is Rock Port.^[2] It was originally known as Allen County when it was detached from Holt County in 1843.^[3] The county was officially organized on February 14, 1845, and named for U.S. Senator David Rice Atchison from Missouri.^[4]

According to the U.S. Census Bureau, the county has a total area of 550 square miles (1,400 km²), of which 547 square miles (1,420 km²) is land and 2.8 square miles (7.3 km²) (0.5%) is water.^[5]

Atchison's western boundary for the most part is the Missouri River and Nebraska. An 1867 flood straightened a bend in the river north of Watson. Both Nebraska and Missouri claimed the 5,000 acre McKissick Island that extends almost two miles into Atchison County. The Supreme Court in 1904 decided that the land belongs to Nebraska. The only way Nebraskans can reach it by road is to cross the Missouri River and then travel through Missouri.^[6]

The State Line Slough (Missouri) stream is in Atchison County.

At the presidential level, Atchison County is solidly Republican. Atchison County strongly favored Donald Trump in both 2016 and 2020. Bill Clinton was the last Democratic presidential nominee to carry Atchison County in 1992 with a plurality of the vote, and a Democrat hasn't won majority support from the county's voters in a presidential election since Lyndon Johnson in 1964.

Like most rural areas throughout northwest Missouri, voters in Atchison County generally adhere to socially and culturally conservative principles which tend to influence their Republican leanings. In 2018, Missourians voted on a proposition (Proposition A) concerning right to work, the outcome of which ultimately reversed the right to work legislation passed in the state the previous year. However, 57.61% of Atchison County voters cast their ballots to keep the law.

The 2020 presidential primaries for both the Democratic and Republican parties were held in Missouri on March 10. On the Democratic side, former Vice President Joe Biden (D-Delaware) both won statewide and carried Atchison County by a wide margin. Biden went on to defeat President Donald Trump in the general election.

Incumbent President Donald Trump (R-Florida) faced a primary challenge from former Massachusetts Governor Bill Weld, but won both Atchison County and statewide by large margins.

The 2016 presidential primaries for both the Republican and Democratic parties were held in Missouri on March 15. Businessman Donald Trump (R-New York) narrowly won the state overall and carried a plurality of the vote in Atchison County. He went on to win the presidency.

On the Democratic side, Senator Bernie Sanders (I-Vermont) carried Atchison County, but former Secretary of State Hillary Clinton (D-New York) won statewide by a small margin. Clinton won the nomination that year.

The 2012 Missouri Republican Presidential Primary's results were nonbinding on the state's national convention delegates. Voters in Atchison County supported former U.S. Senator Rick Santorum (R-Pennsylvania), who finished first in the state at large, but eventually lost the nomination to former Governor Mitt Romney (R-Massachusetts). Delegates to the congressional district and state conventions were chosen at a county caucus, which selected a delegation favoring Santorum. Incumbent President Barack Obama easily won the Missouri Democratic Primary and renomination. He defeated Romney in the general election.

In 2008, the Missouri Republican Presidential Primary was closely contested, with Senator John McCain (R-Arizona) prevailing and eventually winning the nomination.

Then-Senator Hillary Clinton (D-New York) received more votes than any candidate from either party in Atchison County during the 2008 presidential primary. Despite initial reports that Clinton had won Missouri, Barack Obama (D-Illinois), also a Senator at the time, narrowly defeated her statewide and later became that year's Democratic nominee, going on to win the presidency.
