The Nepal house martin (Delichon nipalense)[2] is a non-migratory passerine of the swallow family Hirundinidae.

[3] This martin has a distinctive subspecies, D. n. cuttingi, described by American biologist Ernst W. Mayr in 1941 from a specimen taken near the Burma-Yunnan border.

[6] White-throated birds in the southern extension of the range are similar in appearance to the nominate subspecies, but because of their geographical separation are sometimes considered to be a third race, D. n.

[7] Delichon is an anagram of the Ancient Greek term χελιδών (chelīdōn), meaning "swallow",[8] and nipalense refers to Nepal, where the type specimen was obtained.

[4] The nominate subspecies D. n. nipalense breeds in the Himalayas from Garhwal east through Nepal, north-eastern India and Bangladesh as far as western Myanmar.

The Nepal house martin is largely resident, but may move to lower altitudes when not breeding, and has been occasionally recorded in northern Thailand in winter.

[11][6] The range of this species overlaps with that of the nominate subspecies of Asian house martin, although they breed at different altitudes.

[7] The Nepal house martin breeds between March and July, with some variation in timing depending on locality, and usually raises two broods.

It normally builds its nest, a deep mud bowl lined with grasses or feathers, under an overhang on a vertical cliff.

Since the range is more than 20,000 square kilometres (7,700 sq mi), and there are more 10,000 mature individuals, in the absence of any large decline in distribution or numbers the species does not appear to meet the criteria to be considered vulnerable, and is currently evaluated as Least Concern by the IUCN.
