Sermiligaaq (old spelling: Sermiligâk´) is a settlement in the Sermersooq municipality in southeastern Greenland.

[2] In Kalaallisut, its name means "Beautiful Glacierfjord".

The small island of Quujuutilik (also spelled Kujutilik or Qûjûtilik) is located off the coast northeast of Sermiligaaq.

[3] The settlement is served by the Sermiligaaq Heliport.

The population of Sermiligaaq has slowly increased in the last two decades, unlike in the neighboring settlements of Kuummiit and Kulusuk.
