William Mason (1725 – 1797) was an English poet, editor and gardener.

He was born in Hull and studied at St John's College, Cambridge. He was ordained in 1754 and held a number of posts in the church.

Among his works, none of them highly regarded today, are the historical tragedies Elfrida (1752) and Caractacus (1759) and a long poem on gardening, The English Garden (three volumes, 1772-82). His garden designs included one for the 2nd Earl of Harcourt. He published the Life and Letters of Thomas Gray, a friend who was a great influence on his own work, in 1774.
