Giles Robertson Harding Easterbrook (3 January 1949 – 1 September 2021) was a British composer, musician and music publisher.
He was educated at Purley Grammar School and Worcester College, Oxford, where he switched subjects from Ancient Egyptology and Coptic to music after receiving some private tuition from Kenneth Leighton.

He helped set up the Kenneth Leighton Trust, worked with Lady Bliss to establish the Bliss Trust in 1986,[2] and promoted and edited some early works by Constant Lambert, including the early Piano Concerto and the ballet Mr Bear-Squash-You-All-Flat (1924).
