Lanford Wilson, American playwright, co-founded the Circle Repertory Company (died 2011)

Lanford Wilson was an American playwright. His work, as described by The New York Times, was "earthy, realist, greatly admired [and] widely performed". Wilson helped to advance the off-off-Broadway theater movement with his earliest plays, which were first produced at the Caffe Cino beginning in 1964. He was one of the first playwrights to move from off-off-Broadway to off-Broadway, then Broadway and beyond.

The Circle Repertory Company, originally named the Circle Theater Company, was a theatre company in New York City that ran from 1969 to 1996. It was founded on July 14, 1969, in Manhattan, in a second floor loft at Broadway and 83rd Street by director Marshall W. Mason, playwright Lanford Wilson, director Rob Thirkield, and actress Tanya Berezin, all of whom were veterans of the Caffe Cino. The plan was to establish a pool of artists — actors, directors, playwrights and designers — who would work together in the creation of plays. In 1974, The New York Times critic Mel Gussow acclaimed Circle Rep as the "chief provider of new American plays."
