Petherton Park (also known as North Petherton Park or Newton Park) was a Deer park around North Petherton within the English county of Somerset. The origins are unclear but the area was part of an earlier Royal Forest stretching from the River Parrett to the Quantock Hills. According to the late 13th century Hundred Rolls, King Henry II of England (d. 1189) gave William of Wrotham lands at North Petherton. During the reigns of Henry II (1154–1189) and Richard I (1189–1199), the royal forest of Petherton Park, was held from the crown by Osbert and William Dacus by grand serjeanty of being the king's Forester of Petherton. William de Plessis, who died in 1274 was granted Petherton Park and it was inherited by his son Richard de Barbeflote or Plessis.
