Pickersgill's reed frog (Hyperolius pickersgilli), also known as Avoca reed frog, is a species of frog in the family Hyperoliidae. It is endemic to South Africa. It occurs in the coastal lowlands of KwaZulu-Natal between Sezela and St Lucia. Description Adult males grow to usually no more than whereas adult female can approach in snout–vent length. The snout is acutely pointed. The tympanum is hidden. The toes are webbed. There are two colour phases. Juveniles and males are dorsally light to dark brown.

The feet and concealed parts of the limbs are yellow, while the throat and the ventrum are yellowish to white. Females change to the female colour phase at length of . The dorsum becomes green, eventually light to yellowish green, whereas the dorso-lateral stripes become indistinct and eventually disappear.

Males have a gular vocal sac that has a well-developed protective flap over it. The male advertisement call is a quiet slow creak that could be mistaken for an insect call.
