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 Hot L Baltimore is a 1973 American play by Lanford Wilson set in the lobby of the Hotel Baltimore. The plot focuses on the residents of the decaying property, who are faced with eviction when the structure is condemned. The play draws its title from the hotel's neon marquee with a burned-out "e" that was never replaced.
