Wu'ayra Castle is a ruined Crusader castle located in Wadi Musa, Jordan, 1 kilometre north of the main entrance to Petra. It was founded by Baldwin I of Jerusalem as an outpost of the larger Montreal Castle, which stands about 34 kilometres north of it at Shoubak. The area is extremely rugged and difficult to access.
The name given to the castle by its Crusader builders was Castellum Vallis Moysis or li Vaux Moysi, both meaning '[Castle of] Moses Valley' in Medieval Latin and Old French, respectively, mirroring the name of the valley, Wadi Musa in Arabic.
During their rule, the Crusaders built several castles and forts from Antioch in the north, to Karak, Montreal (Shawbak), and the Petra region to the south. At Petra, Baldwin I, king of the Latin Kingdom of Jerusalem, built the fortress of Al-Wua'yra to be able to control the area extending southeast of the Dead Sea. This allowed him to control the commercial, military and Muslim pilgrimage roads between the Levant, Egypt, and the Hijaz. The forces of Sultan Saladin (Salah ad-Din) conquered the castle in AD 1188, shortly after also taking Montreal Castle. The castle was deserted and was only known to the inhabitants of the area already in the 1220s.

In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654.
