Lake is an "L" station on the CTA's Red Line in the Chicago Loop that is part of the State Street subway.

In 2019, Lake had an average of 19,364 weekday passenger entries, making it the busiest 'L' station.

On November 20, 2009, the Chicago Pedway connecting the unpaid portions of Lake and Washington stations reopened to service.

The two were separated on June 2, 1996, due to the renovation project of the Randolph-Washington mezzanine and Lake became an independent station on November 18, 1997, in order to better facilitate transfers between the Red Line subway and the elevated State/Lake station.
