The Washington County Fair is an annual event held at the Washington County Fairgrounds in Hillsboro, Oregon, United States. The fair includes amusement rides, live entertainment, exhibits, and other exhibits. It is held during the last weekend of July.

Pop singer Britney Spears performed at the fair in 1999. In 2012, singer/actress Miranda Cosgrove headlined the entertainment. Due to the planned attendance of the Blue Angels at the Oregon International Air Show, the fair overlapped with the air show in 2013 creating traffic issues with the air show held across Cornell Road at the Hillsboro Airport. The 2015 fair featured hip-hop artist Flo Rida as the main performer. During the 2016 fair, several people reported contracting E. coli, which led to the fair not allowing visitors to pet animals at the 2017 fair.
