Ceratomegilla undecimnotata is a species of black-spotted lady beetle belonging to the family Coccinellidae, subfamily Coccinellinae.

Ceratomegilla undecimnotata can reach a length of about 5–7 millimetres (0.20–0.28 in).

Elytra are orange-red, while pronotum is black, sometimes with a small white line at the front edge.

This species can be confused with Coccinella septempunctata, but it is smaller and more oval, the central spot above the pronotum is more triangular than round and there is no white around it.

This quite rare species can be found in central and southern Europe.
