Larix griffithii, the Sikkim larch, is a species of larch, native to the eastern Himalaya in eastern Nepal, Sikkim, western Bhutan and southwestern China (Xizang, Yunnan), growing at 1,800–4,100 metres (5,900–13,500 ft) in altitude.

The crown is slender conic; the main branches are level to upswept, the side branchlets pendulous from them.

The leaves are needle-like, light glaucous green, 2–4 cm (1–2 in) long; they turn bright yellow to orange before they fall in the autumn, leaving the pale yellow-brown shoots bare until the next spring.

The old cones commonly remain on the tree for many years, turning dull grey-black.

Trees to the northeast of the range in eastern Bhutan and Xizang have been separated as Larix kongboensis (Mill 1999); they differ in smaller cones 3–5 cm (1–2 in) long.
