North Sinai Governorate (Arabic: محافظة شمال سيناء‎ Muḥāfaẓat Shimāl Sīnāʾ) is one of the governorates of Egypt. It is located in the north-eastern part of the country, and encompasses the northern half of the Sinai Peninsula. It is bordered in the north by the Mediterranean Sea, in the south by South Sinai Governorate, in the west by Port Said, Ismailia, and Suez Governorates, and in the east by the Gaza Strip and Israel. Its capital is the city of Arish. A governorate is administered by a governor, who is appointed by the President of Egypt and serves at the president's discretion.

The population of the North Sinai Governorate as at 2014 was 421,984 people, predominantly Bedouin tribesmen. The Governorate covers an area of 27,574 square kilometers. The population density is 15 inhabitants per square kilometer.

A significant economic activity of the Bedouin tribes has been smuggling. They have been active in the smuggling of supplies and weapons into the Gaza Strip by way of cross-border tunnels as well as assisting illegal migrants into Israel. These activities have been curtailed by the Egyptian government crackdown of smuggling into the Gaza Strip and by the building of the Israel-Egypt barrier.
