Allodaposuchidae is an extinct clade of eusuchians that lived in Europe during the Late Cretaceous (Santonian-Maastrichtian).

[1][2][3] The type genus, Allodaposuchus, was originally described in 1928 by Nopcsa from the Maastrichtian-age Sard Formation of the Hațeg Basin in Transylvania, Romania, and classified as a relative of the North American Leidyosuchus.

[2][3][6][7][8] Narváez et al. cladistically defined Allodaposuchidae in 2015 as Allodaposuchus precedens and all crocodyliforms more closely related to it than to Hylaeochampsa vectiana, Shamosuchus djadochtaensis, Borealosuchus sternbergii, Planocrania datangensis, Alligator mississippiensis, Crocodylus niloticus, or Gavialis gangeticus.

[2] Other studies have alternatively recovered them not as sister taxon, but rather as an evolutionary grade towards Crocodylia, with Hylaeochampsidae more basal than Allodaposuchidae.

[10][9] Alternatively, a 2021 analysis incorporating postcranial information recovered Allodaposuchidae within Crocodylia.
