William Paulet, 4th Marquess of Winchester (bef. 1560 – 4 February 1629) was an English nobleman, the son of William Paulet, 3rd Marquess of Winchester and Anne or Agnes Howard. He was styled Lord St. John from 1576 to 1598. He was summoned to Parliament on 16 January 1581 in his father's barony as Lord St. John. On 24 November 1598, he succeeded his father as 4th Marquess of Winchester.
