Suez is a seaport city in north-eastern Egypt, located on the north coast of the Gulf of Suez on the Red Sea, near the southern terminus of the Suez Canal, and is the capital of the Suez Governorate. It has three ports: the Suez Port, al-Adabiya, and al-Zaytiya, and extensive port facilities. Together they form a metropolitan area, located mostly in Africa with a small portion in Asia.

The Gulf of Suez is a gulf at the northern end of the Red Sea, to the west of the Sinai Peninsula. Situated to the east of the Sinai Peninsula is the smaller Gulf of Aqaba. The gulf was formed within a relatively young but now inactive Gulf of Suez Rift rift basin, dating back about 26 million years. It stretches some 300 kilometres (190 mi) north by northwest, terminating at the Egyptian city of Suez and the entrance to the Suez Canal. Along the mid-line of the gulf is the boundary between Africa and Asia. The entrance of the gulf lies atop the mature Gemsa oil and gas field. The gulf is considered one of the world's important maritime zones due to being an entrance to the Suez Canal.
