The West Ankeny Car Barns Bay E is a former streetcar carbarn in Portland, Oregon, that is listed on the U.S. National Register of Historic Places.

Completed in 1911,[1][3] it was one of three buildings that collectively made up the Ankeny Car Barns complex[4] of the Portland Railway, Light and Power Company (PRL&P), the owner and operator of Portland's streetcar system at the time.

By 1978, the brick building had become the only surviving structure from the Ankeny complex and one of only two surviving remnants of carbarn complexes of the Portland area's large street railway and interurban system of the past, the other being the PRL&P's Sellwood Division Carbarn Office and Clubhouse.

[3] The original Ankeny carbarn was built in 1892 by the City and Suburban Railway Company, one of PRL&P's predecessors.

The complex was expanded in 1901 and 1910 through the construction of additional buildings, including Bays D and E, located west of 28th Avenue between Burnside and Couch streets.
