The Afghan Snowfinch (Montifringilla theresae) is a bird of the sparrow family and is an Afghan endemic found only in the Hindu Kush. The species was named by Richard Meinertzhagen after his companion, Theresa Clay, who was an expert on bird lice.

It is 13.5-15 cm long. The male is grey-brown with some white in the wings and a black face mask. The female is a buff-tinged brown, with a weaker, greyer face mask and less white in the wings.
