Ludodactylus (meaning "play finger") is a genus of anhanguerid pterodactyloid pterosaur from the Early Cretaceous period (Aptian stage) of what is now the Crato Formation of the Araripe Basin in Ceará, Brazil.

[2] Ludodactylus is based on holotype SMNK PAL 3828, a skull missing part of the head crest, that was removed from the plate before the fossil was illegally sold.

In 2014 however, Brian Andres and colleagues, in a large cladistic analysis of pterosaurs, found Ludodactylus to be slightly more closely related to ornithocheirids and anhanguerids than to Brasileodactylus.

[3] In 2020, a different topology by Borja Holgado and Rodrigo Pêgas recovered Ludodactylus within the family Anhangueridae, more specifically to the subfamily Anhanguerinae, sister taxon to both Caulkicephalus and Guidraco.
