William Guidott (1671–1745) was an English Member of the Parliament of Great Britain. ^[1]

He was born the eldest son of William Guidott of Wootton St. Lawrence, Hampshire. He matriculated from New Inn Hall, Oxford University, on 22 March 1685, aged 14, and in 1686 became a student of Lincoln's Inn. He succeeded his uncle as lawyer to the Marlborough family and was also Steward of Andover from 1703 to his death.

He was elected Member of Parliament for Andover for seven parliaments between 1708 and 1727.

He married three times. His third wife was Patience Soper and they lived in Preston House, which he built at Preston Candover near Basingstoke and Andover. He left no children and on the death of his wife in 1749 Preston Candover passed to their kinsman and heir William Woodroffe, who adopted the name of Guidott.^[2]
