The Rwenzori double-collared sunbird (Cinnyris stuhlmanni), also called Stuhlmann's sunbird or the Rwanda double-collared sunbird, is a species of bird in the family Nectariniidae.

It is sometimes considered to be a subspecies of the greater double-collared sunbird (Cinnyris afer). Some authors consider this bird to be part of a species complex with Cinnyris afer, where it joins Ludwig's double-collared sunbird (Cinnyris ludovicensis) and Prigogine's double-collared sunbird (Cinnyris prigoginei).

GBIF citizen-science records
It is estimated from how often the Stuhlmann's Sunbird is recorded against all the birds logged in Nyungwe National Park (279 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
