William Wolstenholme (24 February 1865 in Blackburn, Lancashire – 23 July 1931 in London) was an English composer and organist.
Wolstenholme was the first blind musician to take the degree since John Stanley.
He was a close friend of the other noted blind organist Alfred Hollins and was also well known as a recitalist.
Wolstenholme's devoted sister Maud acted as his secretary and amanuensis for most of his life.
