The tiny sunbird (Cinnyris minullus) is a species of bird in the family Nectariniidae.

There is an olive-yellow supercilium over the eye, the throat is grey and the underparts are olive washed with yellow.

The eyes in both sexes are dark brown and the beak and legs are black.

It forages in the canopy singly or in pairs, and sometimes joins small, mixed species flocks.

However it is rare in Nigeria, mainland Equatorial Guinea and Uganda, while being common in the Democratic Republic of Congo.
