Natar Ungalaaq (born 1959) is a Canadian Inuit actor, filmmaker and sculptor whose work is in many major collections of Inuit art. Before playing the lead roles in Atanarjuat: The Fast Runner (2001) and The Necessities of Life (Ce qu'il faut pour vivre) (2008), Ungalaaq played major roles in other Canadian and American films, including Kabloonak (1995), Glory & Honor (1998) and Frostfire (1994). He is also a producer and director of the Inuit Broadcasting Corporation.

Ungalaaq was the carving buddy of director Zacharias Kunuk. With funds raised by selling their handmade work, they bought their first camera gear in 1981, and started a production company in an Inuit community that didn't even have a TV.

His carving in white soapstone, "Sedna with a Hairbrush 1985", is featured in the National Gallery of Canada's collection.In 2016, he made his debut as a director, codirecting the film Searchers with Kunuk.
