Jonas Arthur Berry (December 16, 1904 – September 27, 1958) was a Major League Baseball relief pitcher.

The 5 ft 10+1⁄2 in (1.79 m), 145 lb (66 kg) right-hander played for the Chicago Cubs, Philadelphia Athletics, and Cleveland Indians.

The 39-year-old rookie won 10 games in relief and saved 12 more, tying for the league lead in that category.

He also led the league with 47 games finished, and his earned run average was 1.94.

On July 1, 1946, Berry was purchased from the A's by the Cleveland Indians and continued to be effective, but not as good as he had been the previous two years.
