Harpendyreus is a genus of butterflies in the family Lycaenidae.

Small butterflies (wingspan 17–24 millimetres) with rounded wings without a tail at the back. The upper parts of the males are bright blue to reddish-violet, often with a small, black spot at the hind corner of the hindwing. The underparts are reddish-brown with slightly darker transverse bands, but without black spots.

The species are found along rivers and streams in high-altitude forests. The larvae feed on various low herbs, including lady's mantle , mints and sage.

The genus is distributed in sub-Saharan Africa, mostly in the eastern and southern parts.
