Tallurutiup Imanga National Marine Conservation Area is an approved National Marine Conservation Area (NMCA) located in the Qikiqtaaluk 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-managed protected area and the second largest protected area in Canada after Tuvaijuittuq Marine Protected Area.
