Ulaan Taiga (, lit. "red taiga") is a mountain range in northwestern Khövsgöl, Mongolia, between the Darkhad Valley and Mongolia's border with Tuva, Russia. The range covers parts of the Ulaan-Uul, Tsagaannuur and Bayanzürkh sums. Notable peaks include Mt. Lam Taiga (2619m) and Mt. Belchir (3351m). The Shishged River and the Delgermörön have their sources in this area. A part of the area along the border with Tuva has been put under natural protection.
