The Hilliard Ensemble was a British male vocal quartet originally devoted to the performance of early music. The group was named after the Elizabethan miniaturist painter Nicholas Hilliard. Founded in 1974, the group disbanded in 2014.

The group was founded by Paul Hillier, Errol Girdlestone, Paul Elliott, and David James, although the membership was flexible until Hillier left in the late 1980s. Since 1990 the core members were David James (counter-tenor), Rogers Covey-Crump (tenor/high tenor), John Potter (tenor), and Gordon Jones (bass), with one change: in 1998 John Potter was replaced by Steven Harrold.

The Hilliard Ensemble, under Paul Hillier, had an extensive discography with EMI's Reflexe early music series during the 1980s. The ensemble has since recorded mainly for the ECM label. In 1994, when popular interest in Gregorian chant was at its height, the ensemble released the CD Officium, an unprecedented collaboration with the Norwegian saxophonist Jan Garbarek. The disc became one of ECM's biggest-selling releases, reaching the pop charts in several European countries and receiving five gold discs in sales. Officium's sequel, the 2-CD set Mnemosyne, followed in 1999. The third album, Officium Novum, was released in 2010.

In 2005 the ensemble took part in the Rheingau Musik Festival's composer's portrait of Arvo Pärt, together with the Rostock Motet Choir.

In 2008, The Hilliard Ensemble premiered Heiner Goebbels' avant-garde staged concert "I went to the house but did not enter" at the 2008 Edinburgh International Festival, repeated at the Berliner Festspiele.

In 2009 the ensemble premiered five new works: Guido Morini's Una Iliade, Fabio Vacchi's Memoria Italiana, Steffen Schleiermacher's Die Beschwörung der Trunkenen Oase, Simon Bainbridge's Tenebrae and Wolfgang Rihm's Et Lux.

In September 2010, The Hilliard Ensemble joined the London Philharmonic Orchestra and Choir for the world premiere of Matteo D'Amico's Flight from Byzantium at the Royal Festival Hall, London. They also performed three pieces by Guillaume Dufay: Moribus et genere, Vergene bella and Lamentatio sanctae matris ecclesiae Constantinopolitanae.

The Hilliard Ensemble decided to disband after 41 years and gave their final concert on 20 December 2014 at London's Wigmore Hall. Wikipedia
