William Marsden Hind (21 February 1816, Ballynure - 13 September 1894, Honington, Suffolk) was an English botanist.
He was ordained as a minister of the Church of Ireland in 1841 initially working as a curate at Derriaghy, County Antrim.
His book The Flora of Suffolk (1889) was the climax of a lifelong contribution to botany produced while he was vicar of All Saints Church, Honington.
He went into business with John Mulholland, providing the technical engineering knowledge to establish a highly profitable wet flax spinning mill in Belfast.
In later life William became embroiled in a family dispute which led to a long court case in Dublin in which he lost several thousand pounds of investments in the firm.
