The mountain fulvetta (Alcippe peracensis) is a 14 to 15.5 cm long species of bird in the Alcippeidae family. It is found in Cambodia, Laos, Malaysia, Thailand, and Vietnam in subtropical or tropical moist montane forests.

The black-browed fulvetta, Alcippe grotei, is sometimes considered to be conspecific with mountain fulvetta, but the two forms differ in morphology and vocalisations, and are separated altitudinally. Black-browed fulvetta occurs primarily below 400 m, and mountain fulvetta above 900 m.

Both have a warm brown back and tail, whitish underparts, a grey face and a slate grey crown bordered below with a black line, but black-browed has brown flanks and a weaker white eyering.

Mountain has a yi-yuii-uwee-uwee song, whereas black-browed's is yu-chi-chiwi-chuwoo, yu-uwit-ii-uwoo.
