Sir John Wood (died 20 August 1484) was Speaker of the House of Commons of England between January 1483 and February 1483.
He was probably born in Sussex, the son of another John Wood.
In 1444 he began a long career in the Treasury, holding the offices of under-treasurer of the exchequer (1452–1453 and 1480–1483), Keeper of the Great Wardrobe of the Household (c. 1458–1460), and Treasurer of the Exchequer (1483–1484).
He was appointed High Sheriff of Sussex and Surrey for 1475 and was elected knight of the shire for Sussex in 1449 and for Surrey in 1460 and 1478. During the latter Parliament he was elected speaker of the house for a brief period in 1483, after which he was knighted.
He died in 1484. He had married twice: firstly Elizabeth, daughter and coheir of John Mitchell, Lord Mayor of London, and widow of the former royal physician Thomas Morstede, and secondly Margery, daughter of Sir Roger Lewkenor of Trotton in Sussex. He had no children.
