齿翼鸟（学名odontopteryx）是一种已灭绝的鸟，可能是鹈鹕和鹳的近亲，生存于始新世，化石发现于欧洲和非洲。

齿翼鸟是长齿海鸟，在颚的切割上长有独特的齿形突出物，在小型的齿鸟中，这些突出物明显倾斜，其形式与基础小的鹈鹕相似，翼展长达5米，异名有neptunavis，头骨在1873年被Richard owen所描述。

Odontopteryx is a genus of the prehistoric pseudotooth birds or pelagornithids. These were probably rather close relatives of either pelicans and storks, or of waterfowl, and are here placed in the order Odontopterygiformes to account for this uncertainty.
