The Suez Canal (Arabic: قناة السويس‎ Qanāt al-Sūwais), also known by the nickname "The Highway to India", is an artificial sea-level waterway in Egypt, connecting the Mediterranean Sea and the Red Sea. Opened in November 1869 after 10 years of construction work, it allows transportation by water between Europe and Asia without navigation around Africa. The northern terminus is Port Said and the southern terminus is Port Tawfik at the city of Suez. Ismailia lies on its west bank, 3 km (1.9 mi) north of the half-way point.

When first built, the canal was 164 km (102 mi) long and 8 m (26 ft) deep. After multiple enlargements, the canal is 193.30 km (120.11 mi) long, 24 m (79 ft) deep and 205 metres (673 ft) wide as of 2010. It consists of the northern access channel of 22 km/14 mi, the canal itself of 162.25 km/100.82 mi and the southern access channel of 9 km/5.6 mi.

The canal is single lane with passing places in Ballah By-Pass and in the Great Bitter Lake. It contains no locks; seawater flows freely through the canal. In general, the canal north of the Bitter Lakes flows north in winter and south in summer. The current south of the lakes changes with the tide at Suez.

Suez (Arabic: السويس‎ as Suwais, Egyptian Arabic: [esseˈweːs]) is a seaport city (population ca. 497,000) in north-eastern Egypt, located on the north coast of the Gulf of Suez (a branch of the Red Sea), near the southern terminus of the Suez Canal, having the same boundaries as Suez governorate. It has three harbors, Adabya, Ain Sokhna and Port Tawfiq, and extensive port facilities. Together they form a metropolitan area. Railway lines and highways connect the city with Cairo, Port Said, and Ismailia. Suez has a petrochemical plant, and its oil refineries have pipelines carrying the finished product to Cairo.

In the 7th-century CE a town named "Kolzum" stood just north of the site of present-day Suez and served as eastern terminus of a canal built by Amr ibn al-'As linking the Nile River and the Red Sea. Kolzum's trade fell following the closure of the canal in 770 by the second Abbasid caliph al-Mansur to prevent his enemies in Arabia from accessing supplies from Egypt and the lands north of it. Nonetheless, the town benefited from the trade that remained between Egypt and Arabia. By 780 al-Mansur's successor al-Mahdi restored part of the canal. The Qarmatians led by Hasan ibn Ahmad defeated a Fatimid army headed by Gawhar al-Siqilli at Kolzum in 971 and thereby captured the town. Following his defeat in Cairo by al-Siqilli at the end of that year, Hasan and his forces retreated to Arabia via Kolzum. Suez was situated nearby and served as a source of drinking water for Kolzum according to Arab traveler al-Muqaddasi who visited in 986.
