William Grant Stratton (born February 26, 1914) was a Republican politician who represented the state of Illinois in the United States House of Representatives. Serving as a member of Congress during the 1940s, he held the office of Representative for Illinois at-large, reflecting a statewide constituency rather than a single geographic district.

Stratton began his congressional service on January 3, 1941, and remained in office until January 3, 1949. Over the course of these years, he completed two terms in the House. During this period, he was identified with the Republican Party and participated in the national legislative process as part of Illinois’s at-large delegation. His tenure is recorded as that of a historical, now-former member of Congress from Illinois.
