Congosaurus is an extinct genus of dyrosaurid mesoeucrocodylian.

Fossils have been found from Lândana, in Angola and date back to the Paleocene epoch.

[3][4] It has since been proven a distinct genus of dyrosaurid separate from both Dyrosaurus and Hyposaurus.

[5] In 2007, a new species of Congosaurus was constructed after previously being assigned to Rhabdognathus, and named C. compressus, extending the geographic range of the genus into the present-day Sahara.

[6] Lateromedially compressed teeth show its close relation to C. bequaerti.
