Pterodactylus (/ˌtɛrəˈdæktᵻləs/ TERR-ə-DAK-til-əs, from the Greek πτεροδάκτυλος, pterodaktulos, meaning "winged finger") is an extinct flying reptile genus of pterosaurs, whose members are popularly known as pterodactyls ( /ˌtɛrəˈdæktᵻlz/). It is currently thought to contain only a single species, Pterodactylus antiquus, the first pterosaur species to be named and identified as a flying reptile.

The fossil remains of this species have been found primarily in the Solnhofen limestone of Bavaria, Germany, dated to the late Jurassic Period (early Tithonian), about 150.8–148.5 million years ago, though more fragmentary remains have been tentatively identified from elsewhere in Europe and in Africa.
