The Tytler's Leaf-Warbler (Phylloscopus tytleri) is a species of Old World warbler in the Sylviidae family. It is found in Afghanistan, India, Nepal, and Pakistan. It passes through the Western Himalayas to winter in southern India, particulaly in the Western Ghats and the Nilgiris.
Its natural habitat is subtropical or tropical moist montanes. It is threatened by habitat loss. It breeds in the Northwestern Himalayan region and is suspected to breed in the Garhwal and Kumaon Himalayas.
The name commemorates the British naturalist Robert Christopher Tytler.
In museum specimens, the thin bill is clear and there is a long exposed nasal groove along the bill. The rictal bristles are short and few and the feathering at the base of the beak is reduced giving a very pointed face profile. The lower mandible is not flesh coloured in tytleri as it is found in most trochiloides and it is not dark black as in Phylloscopus collybita tristis. They do not have any wing bars.
