John Longland (died 1547) was the English Dean of Salisbury from 1514 to 1521 and Bishop of Lincoln from 1521 to his death in 1547.
He was King Henry VIII's confessor and was said to have been one of those who first persuaded the King that he should annul his marriage to Katherine of Aragon.
In 1519 he was appointed Canon of the sixth stall at St George's Chapel, Windsor Castle, a position he held until 1520. He was also Lord Almoner from c.1521.
During the English Reformation, he was among the conservative bishops, recognizing Transubstantiation. His conservatism is attested to by his complaint in 1536 to Thomas Cromwell about Protestant preachers in his diocese.
