This is a list of string quartet composers, chronologically sorted by date of birth and then by surname. It includes only composers who have Wikipedia articles. This list is by no means complete. String quartets are written for four string instrumentsusually two violins, viola and cellounless stated otherwise.

Born in the 16th century

 * Gregorio Allegri (1582–1652): The earliest known composition for two violins, viola and cello (although is referred to as "Duoi Violini, Alto, & Basso di Viola") is attributed to him. Scholars often refer to it as "Symphonia" or as a four-part sonata. Still, it is the very first example of a composition for this organic which does not involve the use of a basso continuo, which was unusual for that time.

Born in the 17th century
