Bongor (Arabic: بونقور) is a city in Chad, the capital of the region of Mayo-Kebbi Est.
During the rainy season (May–September), the Logone is navigable between Bongor and N'Djamena, Chad's capital.
In 1904, a military station was founded near Bongor by German colonial officer Herbert Kund, constituting the beginning of the city's modern history.
The city has been an important centre of secondary education since colonial times.
The Lycée Jacques Moudeina is located in the city and many of the future leaders of the nations that became independent after the dissolution of the colony of French Equatorial Africa attended the Lycée.
