The University of Washington Bothell (UW Bothell or UWB) is a campus of the University of Washington and is located in Bothell, Washington. It was founded in 1989 and is one of the three campuses of the University of Washington, alongside the Seattle main campus and UW Tacoma. The campus is located near the junction of Interstate 405 and State Route 522; it is shared with Cascadia College, a public community college.

UW Bothell is led by a chancellor who leads the campus and reports to the president and provost of the University of Washington.

University of Washington Bothell was founded in 1989 when it was granted the approval of the Washington State Legislature, in order to expand access to the University of Washington for students in mainly King and Snohomish counties. The university began with a staff of 12 faculty members and a class of 143 students. Its first classes were held in fall 1990, and its first graduating class ⁠— of three students ⁠— completed their degrees in 1991. The permanent campus was built in the 1990s on a 115-acre (47 ha) cattle ranch that had been previously proposed for a regional shopping mall. Dr. Warren Buck III was appointed the university's first chancellor in July 1999 and served until June 2005. Over the course of his chancellorship, he oversaw the university's transition into a four-year institution and the establishment of its permanent campus in 2000.
