Tallurutiup Imanga National Marine Conservation Area is a proposed National Marine Conservation Area (NMCA) located in the Qikiqtani Region of Nunavut, Canada. The goal of the marine conservation area is to work with local Inuit to conserve the rich biodiversity of Lancaster Sound and its adjacent waterways. Once formally established under the Canada National Marine Conservation Areas Act, it will become the largest Parks Canada and Qikiqtani Inuit Association (QIA) co-managed protected area and the second largest protected area in Canada after Tuvaijuittuq Marine Protected Area.
