Mansoura (Arabic: المنصورة‎ Al Manṣūra, IPA: [elmɑnˈsˤuːɾɑ]) is a city in Egypt, with a population of 480,494. It is the capital of the Dakahlia Governorate.

Mansoura in Arabic means 'victorious'. The city is named after the Egyptian victory over Louis IX of France during the Seventh Crusade.

Mansoura lies on the east bank of the Damietta branch of the Nile, in the Delta region. Mansoura is about 120 km northeast of Cairo. Across from the city, on the opposite bank of the Nile, is the town of Talkha.

Mansoura was established in 1219 by Saladin's nephew, Abu-Bakr Malik ibn al-Adil I (their phater also known as Saphadin) of the Ayyubid dynasty. After the Egyptians defeated the Crusaders during the Seventh Crusade, it was named Mansoura (aka. "The Victorious").

In the Seventh Crusade, the Capetians were defeated and put to flight; between fifteen and thirty thousand of their men fell on the battlefield. Louis IX of France was captured in the main Battle of Mansoura, and confined in the house of Ibrahim ben Lokman, secretary of the sultan, and under the guard of the eunuch Sobih.. The king's brother was imprisoned in the same house. The sultan provided for their sustenance. The house of Ibrahim ben Lokman is now the only museum in Mansoura. It is open to the public and houses articles that used to belong to the French monarch, including his personal thirteenth century toilet.
