James Franklin Stewart (June 11, 1939 – November 24, 2012) was an American Major League Baseball utility man and scout.

After three years in the minor leagues, he came to the majors as a middle infielder, making his Cubs' debut at age 24 on September 3, 1963, in a 16–3 loss to the San Francisco Giants in Candlestick Park.

On November 29, 1971, Stewart was part of the landmark trade that brought Hall of Fame second baseman Joe Morgan, outfielders César Gerónimo and Ed Armbrister, pitcher Jack Billingham and infielder Denis Menke to the Reds; slugger Lee May, Cincinnati second baseman Tommy Helms, and Stewart went to Houston in exchange.

Morgan would win back-to-back National League Most Valuable Player Awards in 1975 and 1976—and lead the Reds to consecutive World Series championships.

He played his final major league game at age 34 on September 29, 1973, and was released by the Astros on October 26.
