William Wolstenholme (24 February 1865 in Blackburn, Lancashire – 23 July 1931 in London) was an English composer and organist.

In 1887 he went to Oxford University where he obtained his degree in Music; here he met with Sir Edward Elgar (1857—1834) who he had first met when he attended college at Worcester. Elgar was to help William throughout his time at University.
Wolstenholme was born blind, but lived a full and active live despite this handicap.
He was a close friend of the other noted blind organist Alfred Hollins and was also well known as a recitalist.

Wolstenholme’s compositions were largely religious in nature and included hymn tunes, anthems, and organ voluntaries. He was known for his ability to craft melodic and harmonically interesting music that was accessible to a broad audience. Some of his compositions include “Concert Overture in F major”, the hymn “O Give Thanks unto the Lord”, and for organ a voluntary “Pastorale” and “Sonata for the Organ in the Style of Handel”.
