The hill swallow is a small passerine bird in the swallow family. It breeds in southern India and Sri Lanka. It is resident apart from some local seasonal movements. This bird is associated with coasts, but is increasingly spreading to forested uplands. It was formerly considered to be a subspecies of the Pacific swallow.

It also uses open country in the lowlands and increasingly occupies forested uplands and tea/coffee estate landscapes. Frequently around human settlements, roads, and bridges where nesting substrates are available. Often forages over rivers, reservoirs, and paddy fields. Tolerant of modified habitats provided there is open airspace and nearby water.

Hill swallows build neat cup-shaped mud nests on sheltered ledges, bridges, and culverts, often reusing sites year after year. They are easily confused with barn swallows but have a much shorter, shallowly forked tail. Formerly treated as a subspecies of the Pacific swallow, they are now recognized as a distinct species restricted to southern India and Sri Lanka.
