Olrik Fjord (Danish: Olriks Fjord; Greenlandic: Kangerluarsussuaq) is a fjord in the Avannaata municipality, Northwestern Greenland. To the east the fjord opens into the Hvalsund, at the end of the Inglefield Gulf of the Baffin Bay.

This fjord was named by Robert Peary after Christian Søren Marcus Olrik, Royal Inspector of North Greenland.

Olrik Fjord runs in a roughly east–west direction with its mouth west of Kangeq, in the southern shore of the mouth of the Inglefield Gulf, where the latter becomes the Hvalsund. It is a long and narrow fjord, having a shape uncommon in NW Greenland. In the area near its mouth the fjord's southern shore is fringed by up to 680 m (2,230 ft) high cliffs displaying multicolored strata.

The Marie Glacier, an offshoot of the Leidy Glacier, discharges at the head of the Olrik Fjord, not far from the head of the Academy Fjord.
