Bongor, town, southwestern Chad, located on the Logone River opposite Dana, Cameroon.
It lies in Chad’s cotton-growing area, and in the 1970s there was some controlled irrigation near the town as part of an effort to develop the rice-growing potential of the Logone floodplain. During the dry season, the area’s wells and pools attract nomads from north of Lake Chad. Bongor has an airport, and the Logone is seasonally navigable between Bongor and N’Djamena. It has health, educational, and other service centres for the surrounding agricultural region. Pop. (2010 est.) 29,400.
