Philip Henry (24 August 1631 – 24 June 1696) was an English Nonconformist clergyman and diarist.
Philip Henry was the eldest son of John Henry, keeper of the orchard at Whitehall, London. His father, son of Henry Williams, was Welsh, born at Briton Ferry, Glamorganshire, on 10 July 1590, and took his father's Christian name as his surname; he rose to be page of the backstairs (a senior personal attendant) to James, Duke of York, and was buried at St. Margaret's, Westminster, on 2 March 1652. His mother, Magdalen, daughter of Henry Rochdale, was baptised at St. Martin's-in-the-Fields on 19 October 1599, and died on 6 March 1645.
