Pleasant Street Station is an aboveground at-grade station on the Green Line "B" Branch of the MBTA subway system in Boston, Massachusetts. It is located in the median of Commonwealth Avenue, on the western side of its intersection with Harry Agganis Way (on the north side) and Pleasant Street (on the south side, extending into Brookline). It serves the western end of the John Hancock Student Village at Boston University.
Pleasant Street is the sixth station for outbound "B" trains after the Blandford Street Incline and the branch's split from the "C" and "D" Branches at Kenmore. It was also a station on the "A" Branch to Watertown until that branch closed in 1969.
It is not related to the Pleasant Street Incline, which was located near the Washington Street Theatre District in central Boston.
