Draigwenia (meaning "white dragon" from the Welsh ddraig wen, referring to a dragon associated with the Anglo-Saxons) is an extinct genus of pterosaur known from a jaw fragment found in the Late Cretaceous Cambridge Greensand in the United Kingdom.

The fossil was likely reworked from an Early Cretaceous layer that can be dated to the Albian.

In 1914 Reginald Walter Hooley moved O. platystomus to Amblydectes.

[2] It was assigned by David Unwin in 2001 to the genus Lonchodectes,[3] and in 2013 was excluded from the Lonchodraconidae.

[4] In a 2021 review of the genus Amblydectes, Borja Holgado considered platystomus a valid taxon and gave it its own genus, Draigwenia, reinterpreting it as an indeterminate member of Lanceodontia.
