Cyrus Walker was a sidewheel tug active in Puget Sound in the second half of the 19th century.

Domingo Marcucci built the Cyrus Walker at San Francisco, California at his Steamboat Point shipyard in 1864, for Pope & Talbot.

She was equipped with two high-pressure steam engines and a surface condenser.

George W Bullene, who put machinery in her at the Pacific Iron Works, then took her up to Puget Sound for towing logs for the Pope & Talbot lumber mill on Puget Sound.
