Ludwig's double-collared sunbird (Cinnyris ludovicensis) or the montane double-collared sunbird, is a small passerine bird which breeds in forested mountains above 1,800 m (5,900 ft) in western Angola as well as the Nyika Plateau of northern Malawi and northeastern Zambia.

[1] This bird is sometimes considered to be con-specific with the greater double-collared sunbird (Cinnyris afer).

The adult male has a glossy, metallic green head, throat upper breast and back with a golden sheen.

The adult female has dark greyish-brown upper parts and a blackish-brown tail.

The chin and supercilium are greyish-buff and the underparts brownish-grey, with the central part of the lower breast and belly being paler or slightly yellowish.
