Alan Huber Lloyd (10 January 1943 – 31 March 1986) was an American composer, primarily known for his scores for the theatrical works of Robert Wilson and the ballets of Andy de Groat.

Lloyd went on to compose incidental piano music for several more early works by Wilson, sometimes performing it himself on stage during the play.

[4] A Letter for Queen Victoria, which premiered in 1974 at the Festival dei Due Mondi, marked the first time that Lloyd composed a full-length score for one Wilson's works.

[6] In addition to his work for Wilson, Lloyd composed ballet music for Andy de Groat and a number of pieces for solo piano and chamber ensemble (mostly string quartets), which he presented in a 1977 concert at The Kitchen in New York City.

His elder sister Phoebe Lloyd (1940–2005) was an art historian who specialised in the life and work of Raphaelle Peale.
