Kapisillit (Danish: Lakskaj) is a settlement in the Sermersooq municipality in southwestern Greenland.

[2] Kapisillit means "the salmon" in the Greenlandic language (Danish: laks, laksen).

[3] The name refers to the belief that the only spawning-ground for salmon in Greenland is a river near the settlement.

[4] Kapisillit is located 75 km (47 mi) northeast of Nuuk, near the head of Kapisillit Kangerluaq,[5] one of the tributary fjords of the 160 km (99.4 mi) long,[6] Nuup Kangerlua, the longest fjord on the Labrador Sea coast of Greenland, and one of the longest in the inhabited part of the country.

The settlement has its own school, church, and grocery store.
