"Don't Sleep in the Subway" is a song written by Tony Hatch and Jackie Trent and recorded by Petula Clark, for whom it was an April 1967 single release.

The song was constructed from three different sections of music previously composed by Hatch; it changes in musical style from pop to symphonic and then, for the chorus, to a Beach Boys-like melody.

In the lyrics the narrator advises her sweetheart against storming out after an argument due to his "foolish pride". If he does, he will "sleep in the subway" or "stand in the pouring rain" merely to prove his point. Although in Scotland there has long existed the Glasgow Subway metro line, in England the term "subway" refers to a pedestrian underpass rather than to an underground transit system. Hatch employed the term in the North American sense. According to the song's co-writer Jackie Trent the title lyric was suggested by the 1961-62 Broadway musical Subways Are For Sleeping.

'Don't Sleep in the Subway' peaked at #5 on the US charts in June 1967, becoming Clark's final US Top Ten single and the second of two #1 hits on the Billboard Easy Listening chart, following 'I Couldn't Live Without Your Love'. In the UK where her precedent single 'This Is My Song' had afforded Clark her best chart showing with two weeks at #1 'Don't Sleep in the Subway' had a July 1967 chart peak of #12, evincing a decline in Clark's UK chart profile which would continue until Clark made her last UK Top 40 appearance with a new recording, 'Song of My Life' which peaked at #32 in March 1971. (Clark would subsequently peak at #47 UK with 'I Don't Know How to Love Him' in 1972 and in 1988 a remix of her 1964 recording 'Downtown' would peak at #10 UK.) 'Don't Sleep in the Subway' reached #3 in Rhodesia, #5 in Canada, #7 in New Zealand, #10 in South Africa and #16 in Germany. In Australia, it was at #1 on the charts dated 16 and 23 September 1967, marking Clark's final appearance at #1 on an official national chart.
