Vigors's sunbird (Aethopyga vigorsii), Sahyadri sunbird, or western crimson sunbird, is a species of sunbird which is endemic to the Western Ghats of India. It has been considered as a subspecies of the crimson sunbird (Aethopyga siparaja) but it does not have the central tail as elongated and is restricted in its distribution.

The male has a scarlet throat and breast, while the rest of its under parts are uniformly grey. Its wings are grey-brown and lack yellowish-olive edges.{{Cite book|last=Grimmett, Richard|first=Inskipp, Carol and Tim|title=Birds of the Indian Subcontinent|publisher=Christopher Helm|year=2016|isbn=978-8-1933-1509-5|location=India|pages=456}} However, it is yellow on the lower back and tail is bottle green.

The female's upperparts are dark olive, while its underparts are grey. A male who has not yet matured is similar to the female, but it has a dull scarlet throat and breast.

The species is distributed mainly in the northern Western Ghats but has been reported from the Nilgiris.{{cite book|author=Rasmussen PC & JC Anderton| year=2005| title=Birds of South Asia.
