Horsley Priory was a medieval, monastic house in Gloucestershire, England.

Goda owned an estate at Horsley, in 1066. It was granted to Troarn Abbey by Roger de Montgomery before 1086. The original grant was said to provide for a prior, a monk, and a parish chaplain to reside at Horsley.^[1] From those provisions emerged the cell called Horsley Priory.

Troarn Abbey exchanged the priory with Bruton Priory for lands in Normandy in 1260. The priory of Horsley ceased to exist before 1380. Horsley manor was retained by Bruton Priory, until the Dissolution of the Monasteries in 1539. In 1541, Horsley was granted to Thomas Seymour.^[2]
