Marshfield was a rapid transit station on the Chicago "L" in service between 1895 and 1954. Constructed by the Metropolitan West Side Elevated Railroad, it was the westernmost station of the Metropolitan's main line, which then diverged into three branches. Marshfield was also served by the Chicago Aurora and Elgin Railroad (CA&E), an interurban, between 1905 and 1953.

The Metropolitan, one of four companies operating the "L", handed its lines over to the Chicago Elevated Railways (CER) trust in 1911. The companies forming the trust formally merged into the Chicago Rapid Transit Company (CRT) in 1924, which continued operation of the "L" until it was taken over by the publicly-held Chicago Transit Authority (CTA) in 1947. The CA&E was a descendant of the Aurora Elgin and Chicago Railway (AE&C), which split into the CA&E in 1921.

Overhauls to the Metropolitan's lines, planned since the 1930s, replaced the Logan Square branch with a subway to go directly downtown and substitute a rapid transit right-of-way in the median of the Eisenhower for the main line and Garfield Park branch. Construction of these new lines was piecemeal, as was the end of service to Marshfield; Logan Square trains were diverted in 1951, as was Garfield Park and CA&E service in 1953. This left Douglas Park trains as the sole traffic at Marshfield until April 1954, when they too used a temporary right-of-way to go downtown. The Congress Line opened in 1958; the junction that Marshfield had served was maintained between the new line and the Douglas Park branch, but the station prior to this divergence was located on Racine Avenue, significantly to the east of Marshfield Avenue. An entrance to the Medical Center station on the new line was located on Paulina Street, a block west of Marshfield Avenue.
