Theatre Row is the popular name for a section of 42nd Street in New York City which is the location for a number of small theatres; it is also the name of a large theatre complex built in 2000 to house six theatres.

Theatre Row is located in Midtown Manhattan between Ninth and Eleventh Avenues. The name comes from the numerous Off- and Off-Off-Broadway theatres that line the south side of the street. In the 1970s, it was an infamous area of brothels and peepshows, but a campaign to clean up the street was launched. Today, it is dominated by a large complex housing six small theatres: the Beckett, the Acorn, the Clurman, the Kirk, the Lion and the Studio Theatre.

It is currently home to eleven resident theatre companies: The Actors Company Theatre, Alchemy, The Clockwork Theatre, Keen Company, Living Image Arts Theater Company, The New Group, Partial Comfort Productions, Resonance Ensemble, Shakespeare NYC, South Ark Stage, and Theater Breaking Through Barriers.
