The Westside Express Service (WES) is a commuter rail line serving parts of the Portland metropolitan area's Washington and Clackamas counties in the U.S. state of Oregon. Owned by TriMet and operated by Portland & Western Railroad (P&W), it travels 14.7 miles (23.7 km) between Beaverton and Wilsonville along a route just west of Oregon Highway 217 (OR 217) and Interstate 5 (I-5). The line serves five stations and connects with MAX Light Rail at Beaverton Transit Center. Service operates on a 45-minute headway on weekdays during the morning and evening rush hours. In spring 2022, WES saw a daily ridership of 420 passengers or about 109,000 riders annually.

Local officials in Washington County began studying the feasibility of an intercity commuter rail service in 1996, and the Washington County Commuter Rail Project acquired approval from affected jurisdictions in 2002. Construction commenced in 2006 and it opened on February 2, 2009. From the start of the first serious discussions of the idea, it took thirteen years and $166 million to get WES operational.
