Truman A. Greenwood is an American politician and attorney who served in both chambers of the Ohio General Assembly.

Greenwood challenged incumbent Representative Arlene Singer in 1988, and was sworn in on January 3, 1989.

As a result, Greenwood was appointed to fill the vacancy left in the Ohio Senate.

However, only six months into his Senate tenure, Greenwood announced he would resign, citing an inability to spend time with his family.

He serves as outside counsel for the Ohio Attorney General and is the Law Director of Sylvania Township.
