The Alberni Quartet is a British string quartet, whose members have included:
- 1st violin Dennis Simons, then Howard Davis, currently Karin Leishman
- 2nd violin Howard Davis, then John Knight, then Peter Pople, currently Victoria Sayles
- Viola John White, then Berian Evans, then Roger Best, currently Matthew Souter

The quartet was founded in 1962 by four students of the Royal Academy of Music (Dennis Simons, Howard Davis, John White, and Gregory Baron). It was initially named the Simons Quartet, after its first violinist, and later renamed Alberni (the name of Dennis Simons' birthplace in Canada). From 1968 Davis became the 1st violinist, with Peter Pople, Roger Best, and David Smith. They were based in Harlow, Essex where they became established in the 1960s as the town's "quartet in residence", and by the mid-1970s had become world-renowned. Their debut in the Carnegie Hall was well received in the New York Times, and they received positive reviews of their recordings of Schumann's piano quintet, Schubert's string quintet and Brahms' string sextets numbers one and two.
As well as performing a wide range of the classical string quartet repertoire from Haydn and Mozart to Bartók and Benjamin Britten, they performed new works written for them including Richard Stoker's first string quartet at the Buxton Festival in February 1962 and again at the SPNM, 4 St James's Square, London, in March 1963,
