Pallas's leaf warbler breeds in coniferous taiga forests including fir, spruce, pine and larch, or in mixed forest with rhododendron, karsu oak and a high percentage of conifers.
In southern Russia, it was found breeding at up to 1,500–1,700 metres (4,900–5,600 ft).
In winter, it uses a wider range of habitats, including broadleaf forest and scrub as well as conifers, and can be found in river valleys down to 100 metres (330 ft).

Pallas's leaf warbler breeds in Siberia from the Altai Mountains east to the Sea of Okhotsk, northern Mongolia, northeast China and possibly North Korea.
It is strongly migratory and winters mainly in subtropical south China, northern Thailand and elsewhere in northeastern Indochina.
It is rare but annual in Japan.
