Perlerfiup Kangerlua (old spelling: Perdlerfiup Kangerdlua) is a fjord in Avannaata municipality in northwestern Greenland. It is a tributary fjord of the larger Uummannaq Fjord system.

The fjord head at approximately 70°59′30″N 50°57′00″W / 70.99167°N 50.95000°W / 70.99167; -50.95000 is formed by the front of the Perlerfiup Sermia glacier flowing from the Greenland ice sheet (Greenlandic: Sermersuaq). At about one third of its length, the fjord changes direction from westward to northwestward, finally turning sharply to the southwest before confluence with the northeastern part of Uummannaq Fjord at approximately 71°03′10″N 52°00′00″W / 71.05278°N 52.00000°W / 71.05278; -52.00000, due west of Ukkusissat.

The fjord is bounded from the south by the Ukkusissat Peninsula across its entire length. To the north, it is bound by the mainland of Greenland, the highlands of Akularusersuaq and Akuliarusikassak, and the mountains of Perlerfiup Nunaa. The coastline is undeveloped−the fjord has only one tributary fjord on its northern bank, the Qaumarujuk Fjord.

Ukkusissat, perched on the northwestern tip of the Ukkusissat Peninsula at the mouth of the fjord, is the only settlement in the area.

Maamorilik is a former mining site, currently undergoing reactivation, and slated for reopening in November 2010. Holding resources of zinc, iron, lead, and silver, the mine is 5 km (3.1 mi) long, with its entry level situated 750 km (470 mi) above the sea level.

The fjord can be reached by individually chartered boats from Ukkusissat. Ukkusissat Heliport served by Air Greenland is the only aerodrome in the area, with twice-weekly connections to Uummannaq.
