Steppenwolf Theatre Company is a Chicago theater company founded in 1974 by Terry Kinney, Jeff Perry, and Gary Sinise in the Immaculate Conception grade school in Highland Park, Illinois and is now located in Chicago's Lincoln Park neighborhood on Halsted Street. The theatre's name comes from Hermann Hesse's novel Steppenwolf, which original member Rick Argosh was reading during the company's inaugural production of Paul Zindel's play, And Miss Reardon Drinks a Little, in 1974. After occupying several theatres in Chicago, in 1991, it moved into its own purpose-built complex with three performing spaces, the largest seating 550.

A recipient of the Regional Tony Award, several of its productions have transferred to Broadway.

The name Steppenwolf Theatre Company was first used in 1974 at a Unitarian church on Half Day Road in Deerfield. The company presented And Miss Reardon Drinks a Little by Paul Zindel, Rosencrantz and Guildenstern Are Dead by Tom Stoppard, and The Glass Menagerie by Tennessee Williams, with Rick Argosh directing, and Grease by Jim Jacobs and Warren Casey, with Gary Sinise directing.

The founding members are Terry Kinney, Jeff Perry, and Gary Sinise. The founders recruited six additional members: H. E. Baccus, Nancy Evans, Moira Harris, John Malkovich, Laurie Metcalf, and Alan Wilder.

In 1975, Steppenwolf incorporated as a nonprofit organization, saving money by taking the name of a failed theatre company that had already incorporated. In the summer of 1976, Steppenwolf took up residence in a vacant basement space of the Immaculate Conception Catholic Church in Highland Park, Illinois and produced its first full season of plays.

In 1980, the theatre company moved into a 134-seat theatre at the Jane Addams Hull House Center on Broadway Avenue in Chicago. Two years later, the company moved to a 211-seat facility at 2851 N. Halsted Street, which was their home until 1991, when construction was completed on the current theatre complex at 1650 N. Halsted Street (with administrative offices at 1700 N. Halsted Street.) The theatre has three theatres: the Downstairs Theatre that seats 515; the Upstairs Theatre that seats 299; and, the 1700 Theatre, a casual, intimate and flexible theatre that seats 80.

In 1982, the Sam Shepard play True West, starring Sinise and John Malkovich, was the first of many Steppenwolf productions to travel to New York City.

In 1994, the company made its Los Angeles debut with Steve Martin's first play, Picasso at the Lapin Agile.

In 1996, after successful runs in Chicago and New York, Lyle Kessler's Orphans, directed by Gary Sinise, was the first Steppenwolf production to go international, debuting in London.

The MacArthur Foundation awarded Steppenwolf Theatre Company $2.26 million between 1978 and 2017, in support of general operations, and growth of artistic and educational programs.

In 2019, True West opened again at Steppenwolf, for the first time in 37 years, with Namir Smallwood and Jon Michael Hill as the leads and the direction of Randall Arney.
