Major General Roy Ernest Lindquist (February 18, 1907 – November 19, 1986) was a highly decorated senior United States Army officer.

He saw service during World War II and is most noted for his leadership of the 508th Parachute Infantry Regiment (PIR) during the campaign in Western Europe from June 1944 to May 1945.

He also enlisted in the Maine Army National Guard in January 1924 in order to support his effort to be appointed to United States Military Academy.

The 508th Parachute Infantry arrived in Northern Ireland in January 1944 and moved to England in March of the same year, and later participated in the Normandy Campaign, Operation Market Garden and Battle of the Bulge.

After his return to the States, Lindquist attended the National War College in Washington, D.C. After graduation in 1951,[4] he was appointed to the office of Assistant Chief Of Staff within Army Ground Forces.

Now a major general, Lindquist was transferred back to the States and posted to Fort Campbell, Kentucky, before he was appointed a commander of the 3rd Infantry Division in March 1957.
