Tod Daniel Wolters is a retired United States Air Force four-star general who last served as the commander of U.S. European Command and concurrently as NATO's Supreme Allied Commander Europe (SACEUR). He previously served as the commander of U.S. Air Forces in Europe and U.S. Air Forces Africa. He assumed his capstone assignment at the European Command in Germany on May 2, 2019 and at the Allied Command in Belgium on May 3, 2019.

The Supreme Allied Commander Europe (SACEUR) is the commander of the North Atlantic Treaty Organization's (NATO) Allied Command Operations (ACO) and head of ACO's headquarters, Supreme Headquarters Allied Powers Europe (SHAPE). The commander is based at SHAPE in Casteau, Belgium. Effectively SACEUR is the second-highest military position within NATO, below only the Chair of the NATO Military Committee in terms of precedence. There is another Supreme Allied Commander in NATO, Supreme Allied Commander Transformation (SACT), titularly equal, but their duties are less important. SACT, in Norfolk, Virginia, has responsibility for capability development, rather than operations.
