Beatty Creek is a tributary of the Tahltan River in northwest part of the province of British Columbia, Canada.

Beatty Creek's watershed covers 438 km2 (169 sq mi),[5] and its mean annual discharge is 5.73 m3/s (202 cu ft/s).

[6] Beatty Creek originates on the slopes of Meszah Peak, the highest peak of the Level Mountain Range, a cluster of bare peaks on the summit of the massive Level Mountain shield volcano, which forms the most voluminous and most persistent eruptive centre in the Northern Cordilleran Volcanic Province.

As Beatty Creek flows south through Level Mountain and the Nahlin Plateau it collects numerous unnamed tributary streams, some of which also flow through deep valleys carved into Level Mountain.

[8] Beatty Creek supports runs of Chinook salmon and other salmonids.
