Saint Catherine Protectorate is an Egyptian national park in the south of Sinai. It encloses most of the mountainous area of central South Sinai, Mount Catherine at 2,629 meters above sea level.

In 2002, a 640 km2 area demarcated by the ‘Ring Dykke’ within the Protectorate core was listed by UNESCO as a World Heritage Site. The listed area includes the highest mountains in the Protectorate, including Mount Sinai and the Saint Catherine's Monastery.
