Harrison is an "L" subway station on the CTA's Red Line in Printer's Row, Chicago in the Loop.

The layout is typical of most stations from this section, with fare control on a mezzanine level between the street and platform.

On February 9, 2009, an auxiliary entrance at Polk Street that was closed in 1968 was reopened due to an increase of both business and residents living in the South Loop neighborhood.

On April 14, 2014, the Polk Street auxiliary entrance was temporarily closed, reopening on May 25, 2014.

[2] The station entrance at Harrison is located directly in front of Jones College Prep High School.
