The Wind-class icebreakers were a line of diesel electric-powered icebreakers in service with the United States Navy, United States Coast Guard, Royal Canadian Navy, Canadian Coast Guard and Soviet Navy from 1944 through the late 1970s.

Considered the most technologically advanced icebreakers in the world when first built, the Wind-class icebreakers were also heavily armed; the first operator of the class was the United States Coast Guard, which used the vessels for much-needed coastal patrol off Greenland during World War II. Three of the vessels of the class, Westwind, Southwind, and the first Northwind all went on to serve temporarily for the Soviet Union under the Lend-Lease program, while two others were built for the United States Navy and another was built for the Royal Canadian Navy; all eight vessels were eventually transferred to the United States Coast Guard and the Canadian Coast Guard.
