CGS Alaska was a Canadian Government Ship, employed on a survey of Canada's Arctic, in the early 20th century. She was a schooner, built in Alaska, in 1912, and acquired by the Canadian Government, which employed her as part of a fleet of 6 small exploration ships from 1913–1918. She was the only ship that lasted the entire expedition. She was sold in 1918.
The story of her four years with the expedition is outlined in the expedition reports but comes to life in the daily journals of Dr. R.M. Anderson, leader of the Southern Party, who directed her Canadian career, her captains Nahmens and Sweeney, and her engineer Blue.
