Manuel Joseph "Jungle Jim" Rivera (July 22, 1921 – November 13, 2017) was an American professional baseball outfielder.

He played for three Major League Baseball (MLB) teams over ten seasons: St. Louis Browns (1952), Chicago White Sox (1952–1961), and Kansas City Athletics (1961).

Rivera threw and batted left-handed; he stood 6 feet tall and weighed 196 pounds during his playing days.

However, in that year's World Series, which the White Sox lost in six games to the Los Angeles Dodgers, Rivera went hitless in 11 at-bats.

At age 40, Rivera appeared in 64 games for the Kansas City A's during the 1961 season, hitting .241 to cap his career.
