The Little Yalmy River is a perennial river of the Snowy River catchment, located in the Alpine region of the Australian state of Victoria.

The Little Yalmy River rises below Mount Jersey in the Yalmy State Forest in a remote alpine wilderness area and flows generally south, then southwest, then south by west, before reaching its confluence with the Yalmy River within the Snowy River National Park in the Shire of East Gippsland. The river descends 581 metres (1,906 ft) over its 22-kilometre (14 mi) course.

The traditional custodians of the land surrounding the Little Yalmy River are the Australian Aboriginal Bidawal and Nindi-Ngudjam Ngarigu Monero peoples.
