Sanirajak (Inuktitut meaning the shoreline[6]), Syllabics: ᓴᓂᕋᔭᒃ), formerly known as Hall Beach until 27 February 2020,[7] is an Inuit settlement within the Qikiqtaaluk Region of Nunavut, Canada, approximately 69 km (43 mi) south of Igloolik.

It was established in 1957 during the construction of a Distant Early Warning (DEW) site.

Currently the settlement is home to a North Warning System (68°45′44″N 081°13′44″W / 68.76222°N 81.22889°W / 68.76222; -81.22889 (Hall Beach North Warning System (FOX MAIN))) radar facility and the Sanirajak Airport.

In 1971, seven sounding rockets of the Tomahawk Sandia type were launched from Sanirajak, some reaching altitudes of 270 km (170 mi).

Winters are long and extremely cold, lasting most of the year with little chance of a thaw.
