Larix mastersiana is a species of larch in the family Pinaceae. It is found only in western China in west-central Sichuan around Guanxian (now Dujiangyan City) west of the Min River, where it grows at 2,000–3,500 metres altitude. It is threatened by timber harvest and habitat loss. It is a deciduous coniferous tree growing to 20–25 metres tall, with yellow-brown bark on young trees, becoming grey on older trees. The leaves are 12–35 mm (mostly 20–30 mm) long. The cones are 2.5–4.5 cm long, with exserted bracts.[2]

Its status as a distinct species has recently been questioned, as it is genetically nested within the very similar Larix potaninii which occurs in the same area; it may be better treated as a synonym of that species, or a variety of it.[3]
