Ashland is an 'L' station on the CTA's Green and Pink Lines.

The adjacent stations are Damen (Green), which is located about 1⁄2 mile (0.80 km) to the west, Polk (Pink), which is located about 1 mile (1.6 km) to the south, and Morgan station, approximately 3⁄4 mile (1.2 km) to the east.

Ashland station opened on November 6, 1893, as part of the Lake Street Elevated Railroad's initial route,[2] and it is one of the oldest standing stations on the 'L'.

The station closed on April 4, 1948, along with nine other stations on the Lake Street branch,[3] but later reopened on February 25, 1951, the same day the Milwaukee-Dearborn subway opened for service.

Prior to the opening of the Damen station in 2024, Ashland was also the closest "L" station to the United Center, the home stadium of the Chicago Bulls NBA team and the Chicago Blackhawks NHL team.
