Wolterstorffina chirioi is a species of toad in the family Bufonidae.

It is endemic to Cameroon and known only from Mount Oku, its type locality.

[1][3] The specific name chirioi honours Laurent Chirio, a herpetologist from the National Museum of Natural History, France;[2][4] he also collected the holotype.

[2] Wolterstorffina chirioi inhabits Afro-Alpine vegetation and grassland at the summit of Mount Oku at 3,000 metres (9,800 ft) above sea level.

Given its limited high-altitude range, it is potentially affected by climate change too.
