Bridlemile is a Southwest Portland, Oregon neighborhood in the West Hills. The Portland city boundary runs through the neighborhood (aligned with SW Thomas St.) such that the southern part of the neighborhood is within Portland proper, but the northern portion is unincorporated Multnomah County. The portion within Portland city limits extends into Washington County in two places (along Beaverton-Hillsdale Highway, and along Hamilton Road).
The neighborhood is home to Bridlemile Elementary School (SW 47th Dr.) and adjacent Hamilton Park. Bridlemile is a primarily residential neighborhood, though it includes the commercial strip on the north side of Beaverton-Hillsdale Highway.
In 2004 and 2005, the neighborhood associations of Bridlemile and the Southwest Hills Residential League became entangled in an acrimonious dispute over a territory both claim.
Bridlemile includes the historical community of Glencullen, named after early settler Capt. John Winchell Cullen (1838–1939). A station of this name on the Southern Pacific West Side Line operated here from 1923 to 1925.
