Ingerana charlesdarwini is a species of frogs in the family Dicroglossidae. It is endemic to the Andaman Islands, India, and is known from the South Andaman Island, Long Island, and North Andaman Island.

Taxonomy

Later on, specimens labelled as Rana doriae andamanensis collected by Nelson Annandale were found from the Zoological Survey of India. However, Annandale never formally described a taxon using that name, so it is an unavailable name.

Colouration is variable with three different morphs:
Ingerana charlesdarwini have been found in primary evergreen and secondary forests at elevations below. The eggs are laid in water-filled tree holes. It is threatened by habitat loss. The type series was collected in the Mount Harriet National Park, and the species is also known from the Saddle Peak National Park.
