Based on its design featuring a wolf on a map of North America, it is likely the United States Army 2.75” patch.

Very good condition- has hook and loop on the back.

Online research suggest the following:

104th Infantry Division "Timberwolves" patch. This division, nicknamed the "Timberwolves", was first established in 1921 and its shoulder sleeve insignia was inspired by the region of the northwest United States (Oregon) where the division trained before entering combat in World War II. The timberwolf represents the vitality of life in the western states, the tenacity of the division, and the unity of purpose within its ranks.

The patch design was created by Charles Livingston Bull, an artist and wildlife expert. The circular, green patch features a gray timberwolf, specifically a gray wolf in right profile with ears pulled back and snout raised upward.

The 104th Infantry Division played a significant role in World War II, including fighting in the European Theatre, participating in the Battle of the Bulge, and liberating the Mittelbau-dora concentration camp. The division was inactivated after the war in 1945 but later reactivated as the Organized Reserves in 1946.
