HMCS Newington was a commissioned patrol vessel of the Royal Canadian Navy that served in the First World War.

The ship was powered by a steam triple expansion engine, driving one screw creating 58 hp (43 kW) (nominal).

[2] Newington was purchased by the Canadian government in 1908 and converted to a lighthouse supply ship and buoy tender for use in British Columbia waters.

[1] Newington was kept on standby to lay minefields across the entrance to Johnstone Strait until December of that year when the German threat in the Pacific Ocean was nullified.

The vessel was converted to a tugboat and in 1956, was sold to Straits Towing Ltd.[2] On 26 August 1959 she sank in Burrard Inlet, British Columbia.
