79th Street (Chatham) is an electrified commuter rail station along the Metra Electric Main Line in the Chatham neighborhood of Chicago, Illinois. It is located at and over 79th Street, and is 9.9 miles (15.9 km) away from the northern terminus at Millennium Station. In Metra's zone-based fare system, 79th Street is in zone 2. As of 2018, the station is the 212th busiest of Metra's 236 non-downtown stations, with an average of 50 weekday boardings.

East of this station is another Metra Electric station along 79th Street (known as Cheltenham) along the South Chicago Branch. Like much of the main branch of the Metra Electric line, 79th Street-Chatham is built on elevated tracks near the embankment of a bridge over 79th Street. This bridge also carries the Amtrak line that runs parallel to it, carrying the City of New Orleans and Illini and Saluki trains. Parking is available only on the southwest corner of 79th Street and Woodlawn Avenue.

On July 10, 2023, the station was temporarily closed to the public for reconstruction. The project, which will update the station and make the platform ADA-Accessible, is expected to take seven months.

The former Nickel Plate Railroad passed on a long bridge over the Illinois Central (the current tracks) just north of the station.
