John Edward Martin, Sr., (November 15, 1891 – December 9, 1968) was an American politician and jurist from Wisconsin. He was the 16th Chief Justice of the Wisconsin Supreme Court and 29th Attorney General of Wisconsin.

Early life and education
Born in Green Bay, Wisconsin, to Mary Ellen Wigman Martin and Patrick Henry Martin. A Roman Catholic, he was educated at parochial and public schools in Green Bay, graduating from Green Bay East High School in 1909. He attended the University of Wisconsin–Madison and Marquette University, and graduated from Notre Dame Law School in 1916 to become a practicing attorney.

He enlisted in the U.S. Army in August 1917, and was commissioned a Lieutenant after attending officer training at Fort Sheridan, Illinois. He fought in World War I as a First Lieutenant in Company E, 127th Infantry Regiment, 32nd Division. He was wounded during the war, and awarded a Purple Heart. He was honorably discharged as a Captain in 1921. During the war, he served alongside future Wisconsin Supreme Court justices Theodore G. Lewis, Edward J. Gehl, and Roland J. Steinle.

After the war, Martin returned to Green Bay and practiced law, partnering with his father and his uncle, Joseph Martin, who would also later serve on the Wisconsin Supreme Court. In 1933, John was appointed an assistant district attorney in Milwaukee.

In June, 1948, he was appointed to the Wisconsin Supreme Court by Governor Oscar Rennebohm to fill the vacancy created by the death of Justice Chester A. Fowler.
