Whitman County is a county located in the U.S. state of Washington. As of the 2020 census, the population was 47,973.[1] The county seat is Colfax,[2] and its largest city is Pullman.
The county was formed from Stevens County in 1871.[3] It is named after Marcus Whitman, a Presbyterian missionary who, with his wife Narcissa, was killed in 1847 by members of the Cayuse tribe.[4]
Whitman County comprises the Pullman, Washington Metropolitan Statistical Area.
The area delineated by the future Washington state boundary began to be colonized at the start of the nineteenth century, both by Americans and Canadians. However, the majority of Canadian exploration and interest in the land was due to the fur trade, whereas American settlers were principally seeking land for agriculture and cattle raising. The Treaty of 1818 provided for dual control of this area by US and Canadian government officials. During this period, the future Washington Territory was divided into two administrative zones: Clark County and Lewis County (made official in 1845).
The dual-control concept was unwieldy and led to continual argument, and occasional conflict. The status of the Washington area was settled in 1846, when the Oregon Treaty ceded the land south of North latitude 49 degrees to American control.
In 1854, Skamania County was split from the original Clark County. Also in 1854, Walla Walla County was split from the new Skamania County. In 1863, Stevens County was split from Walla Walla County, and in 1871, a portion of Stevens County was set off to form Whitman County. The 1871 shape of Whitman County was considerably larger than its present boundary, as Adams, Franklin, and Lincoln counties were sectioned off from Whitman County in 1883. After that, Whitman County retained its shape, including through the period after Washington became the 42nd state of the Union in 1889.
According to the United States Census Bureau, the county has a total area of, of which is land and (0.9%) is water.[5] Whitman County is part of the Palouse, a wide and rolling prairie-like region of the middle Columbia basin.

Despite the county historically voting for Republicans, Whitman County has a reputation as being far more socially liberal than other counties in Eastern Washington due to the presence of Washington State University in Pullman. It is part of Washington's 5th congressional district and is represented by Republican Cathy McMorris Rodgers. Quite conservative, rural Whitman was one of only three counties in the state to be won by Barry Goldwater in 1964. Since that election, the county has been won by the winning candidate in all but three presidential elections, 1976, 2012, and 2016. Richard Nixon, Ronald Reagan, Bill Clinton, and George W. Bush each won the county twice.
In 2008, Barack Obama received 51.57% of the Whitman County vote.[10] In 2012, he received 46.9% of the vote, with Mitt Romney winning with a 49.7% plurality.[11] Whitman was the only county in eastern Washington to approve same-sex marriage via Referendum 74.

By 2016, the county was considered Democratic in regards to federal elections. Hillary Clinton won the county in 2016 and also voted for Patty Murray in 2016. However, Republican Bill Bryant won this county over incumbent Democrat Jay Inslee by a percentage point in the concurrent gubernatorial election. In the 2020 elections, the majority of the county voted for Democrat Joe Biden for president and re-elected Inslee for governor. Both received majority of the county vote with Inslee becoming the first Democratic gubernatorial candidate to win a county in Eastern Washington since Gary Locke in 2000. However, the county still votes Republican in congressional elections.[12]
In 2020, 52.9% of residents voted for Biden while 42.9% voted for Trump, a 10% margin for Biden.[13]
