43rd is a station on the Chicago Transit Authority's 'L' system in the Grand Boulevard community area in Chicago, Illinois, on the Green Line at 314 E 43rd Street, three blocks east of State Street.

The original station, designed by Myron H. Church, was a brick building with some Queen Anne-style elements.

In July 1959, auxiliary exit stairs were added to the station to streamline passenger traffic on the wharves.

Unlike the entrance to the station the wooden platforms were still the originals of 1892, they were replaced in 1990 during two months of work.

During the renovation of the Green Line from 1994 to 1996, little work was needed as 43rd station received new painting, the porthole on the wall is filled with bricks to be able to put elevators on the platform and make the station accessible to people with disabilities.
