Harold Edwin Darke (29 October 1888 – 28 November 1976) was an English composer and organist.
Darke was born in Highbury, London the youngest son of Samuel Darke & Arundel Bourne and attended Dame Alice Owen's School. While in the RAF he married a violinist, Dora Garland, (the first woman to lead the Queen's Hall Orchestra) at St Michaels, Cornhill on 25 July 1918.
His first organist post was at Emmanuel Church, West Hampstead from 1906 to 1911. He became organist at St Michael's Cornhill in 1916, and stayed there until 1966, leaving only briefly in 1941 to deputise for Boris Ord as Director of Music at King's College, Cambridge during World War II. It is widely accepted that the Cornhill Lunchtime Organ Recitals series begun by Darke in 1916 is the longest-running lunchtime organ concert series in the world; the series has flourished under his successors Richard Popplewell 1966-1979 and the present Organist, Jonathan Rennert, from 1979 to the present. Darke died in Cambridge, aged 88.
His famous setting of Christina Rossetti's In the Bleak Midwinter is often sung at the service of Nine Lessons and Carols at King's College, Cambridge, and at similar services around the world. In the Bleak Midwinter was voted the greatest Christmas carol of all time in a poll of choral experts and choirmasters that was published on 7 December 2008.
Most of his other compositions that are still performed are settings of the Anglican liturgy, especially his three Communion Services in E minor, F, and A minor; and his Magnificat and Nunc Dimittis in F.
