The Ahmed Hamdi Tunnel is a car tunnel under the Suez Canal at Shallufa. The tunnel is named after Ahmed Hamdi, an Egyptian engineer and general martyred in action during the Yom Kippur War. It has two lanes of traffic, one in each direction, and it connects the Asian Sinai Peninsula to the town of Suez on the African mainland.

In 1992, the Japanese government granted aid to a project aimed at rehabilitating the tunnel which had developed leaks. It is long and has an outside diameter of .

The tunnel was part of a major drive to develop the areas surrounding the Suez Canal, including other projects such as the Suez Canal overhead line crossing (completed in 1998), the El Ferdan Railway Bridge, and the Suez Canal Bridge (completed in 2001).
