The Lindsay String Quartet (or The Lindsays) was a British string quartet from 1965 to 2005.

The quartet first performed at the Royal Academy of Music in 1965 to compete for a prize and set out to make the string quartets of Bartók and Beethoven the centre of their repertoire. In 1967, the quartet was appointed to be Leverhulme Scholars at Keele University, and in 1970, it changed its name from the Cropper to the Lindsay String Quartet, naming itself after Lord Lindsay, the founder of Keele University. 1971 brought a change in second violin to Ronald Birks. The quartet gained a Gramophone Award for the Late Beethoven Quartets in 1984. Roger Bigley left the quartet in 1985 to be replaced by Robin Ireland. Bigley then became assistant principal viola of the BBC Philharmonic orchestra before becoming assistant head of strings at the RNCM.
