Maomingosuchus is an extinct genus of gavialoid crocodylian from Late Eocene of Southeast Asia.

[2] The type species, originally Tomistoma petrolica, was named in 1958[3] and was redescribed as Maomingosuchus in 2017.

[4] A second species, Maomingosuchus acutirostris, was described in 2022 from middle-upper Eocence deposits (late Bartonian–Priabonian age, 39–35 Ma) of the Na Duong Basin in northern Vietnam.

[5] It is proposed to be a basal member of Gavialoidea,[1] or alternatively within the family Tomistominae.

[5] It was a relatively small gavialoid with an estimated total length of 3–3.5 metres (9.8–11.5 ft).
