Edward Garrard Marsh (1783–1862) was an English poet and Anglican clergyman.
He was son of the composer John Marsh. He was a good friend of William Hayley, and associated with him and William Blake.
He studied at Wadham College, Oxford, and on graduating became a Fellow of Oriel College, Oxford. He was a curate at Nuneham, and then bought a chapel in Hampstead. He became Residentiary Canon at Southwell. He was vicar of Sandon, Hertfordshire and then Aylesford, Kent. He was Bampton Lecturer in 1848.
At 7 July 1813 he married Lydia Williams (Gosport, England, 17 January 1788 - 13 December 1859) at Southwell, England. She was a sister of Rev. Henry Williams and Rev. William Williams. Their grandfather Rev. Thomas Williams was a Congregational minister.
While he had connections to non-conformist family members, Edward's beliefs followed that of low church evangelical Anglicanism.
He was also from 1821 a prebend of Woodborough, Nottinghamshire, an office suppressed in 1841 by the Church Commissioners.
