CCGS Arpatuuq (Inuktitut: [aʁpatuːq]) is a future Canadian Coast Guard icebreaker under construction at Seaspan Vancouver Shipyards under the Polar Icebreaker Project as part of the National Shipbuilding Strategy. The ship was initially expected to join the fleet by 2017 but has been significantly delayed and is now expected by 2030.

The ship was originally to be named CCGS John G. Diefenbaker after John G. Diefenbaker, Canada's 13th prime minister whose government founded the Canadian Coast Guard in 1962, but the new name was announced on 19 August 2024.
