"Don't Sleep in the Subway" is a song written by Tony Hatch and Jackie Trent and recorded by the British singer Petula Clark, who released it as a single in April 1967.

According to the song's co-writer Jackie Trent the title lyric was suggested by the 1961–62 Broadway musical Subways Are for Sleeping.

[5] Cited by Clark—with "I Couldn't Live Without Your Love"[6]—as her favourite of her hits, "Don't Sleep in the Subway" has also been recorded by Betty Chung, Rita Hovink, Marilyn Maye, Matt Monro, Patti Page, Frank Sinatra, Caterina Valente, and Mari Wilson.

The song's title was used as part of a candidate's name in "Election Night Special", a sketch on Monty Python's Flying Circus: another of that series' episodes featured Cardinal Richelieu (Michael Palin) lip-synching to Clark's record on the show-within-a-show Historical Impersonations.

The song was performed by Rachel Berry (Lea Michele) and Artie Abrams (Kevin McHale) in the 2014 Glee episode "New New York".
