Philip Beaumont (1432–1473), lord of the manors of Shirwell in North Devon and of Gittisham in East Devon, was a member of parliament for a constituency in Devon and was Sheriff of Devon in 1469. He was the rightful heir of his elder brother William Beaumont (1427–1453), a substantial landholder, but faced claims to his inheritance from his bastard nephew, John Bodrugan, "The Beaumont Bastard", the illegitimate son of Joan Courtenay, William's wife.

The Manor of Shirwell was a manor in North Devon, England, centred on the village of Shirwell and largely co-terminous with the parish of Shirwell. It was for many centuries successively the seat of two of the leading families of North Devon, the Beaumonts and their heirs the Chichesters of Raleigh, Pilton, both of which families were seated at the estate of Youlston within the manor of Shirwell. The manor house which survives today known as Youlston Park is one of the most architecturally important historic houses in North Devon and exists largely in its Georgian form, but retains many impressive late 17th-century interiors.
