Dolichochampsa is an extinct genus of eusuchian crocodylomorph.

It is the type genus and only member of the family Dolichochampsidae.

[1] Fossils have been found in the Yacoraite Formation of Argentina and the El Molino Formation of Bolivia of Maastrichtian age.

[3] Because the material associated with the specimens is so fragmentary, its relationships with other eusuchians remain unknown.

[4] Jouve et al. (2020) assigned Dolichochampsa to Gavialoidea, making it the oldest known South American member of this clade.
