St. Paul Street station (MBTA Green Line C branch)

St. Paul Street station is a light rail surface stop on the MBTA Green Line C branch, located in the median of Beacon Street at St. Paul Street in Brookline, Massachusetts. St. Paul Street has two staggered side platforms, serving the C branch's two tracks; the inbound platform is to the west of the intersection, and the outbound platform to the east.

Track work in 2018–19, which included replacement of platform edges at several stops, triggered requirements for accessibility modifications at those stops. Design work for St. Paul Street and seven other C Branch stations was 15% complete by December 2022. Designs shown in February 2024 called for both platforms at St. Paul Street to be shifted to the far side of the intersection. In May 2024, the Federal Transit Administration awarded the MBTA $67 million to construct accessible platforms at 14 B and C branch stops including St. Paul Street. , construction is expected to be complete in fall 2026.
