El Mahmoudia (Arabic: المحمودية, IPA: [elmæħmoˈdejjæ]) is an Egyptian city on the connection point between the Nile and Mahmoudiyah canal.

Because the city is located at the mouth of the Mahmoudiyah Canal, it was considered a key naval transport route for goods and the British weaponry from Alexandria to Cairo to enter boats to the Nile.

In December 1916, local people of the city were celebrating the wedding of a couple, marching in a procession, carrying lamps and torches, and shouting.

The mayor of the city, Darwish al-Wailili, headed a delegation and met with the garrison commander, requesting an apology to the people for the attack.

From July 11, 1942, and throughout World War II, Mahmoudiyah received thousands of displaced people fleeing bombing in Alexandria, Kafr el-Dawar, Khorshid, and al-Baida.

In addition, there is a pump station to raise the Nile water to the canal that supplies several cities in the West Delta, including Alexandria.
