Ctenophora is a genus of true crane flies.

The species are large (about 20 mm long, with 25-mm wingspans), shiny black craneflies with large yellow, orange, or red markings to mimic wasps.

The species are confined to old deciduous forests, orchards, and other habitats with continuity of the presence of dying and fallen trees.

Ctenophora is distinguished from related genera (Dictenidia Brulle, Phoroctenia Coquillett) by these characteristic combinations.

The sides of the mesothorax bear long bristles.
