Junius Alexander Bibbs (October 31, 1910 – September 11, 1980), nicknamed "Rainey", was an American infielder in baseball's Negro leagues from about 1933 to 1944.

Junius Bibbs was born in Henderson, Kentucky to Lloyd Bibbs, a veteran of World War I and first commander of the American Legion Post in Terre Haute, Indiana, and Catherine Carr, whose family had ties to the prominent families of Henderson, including the Powells and the Starlings.

Bibbs' early life was spent growing up in an extended household that included his great-grandmother, Lizzie Powell, a former slave who had amassed some property; his grandfather, James Alexander Carr, whose father had died as a Union Army soldier at the end of the Civil War; and his grandmother Maria Carr, the first African-American librarian in Henderson.

Known as "the only race player on Indiana's collegiate gridiron,"[3] his absence in an October 1935 game is given as a reason for the team's 12–0 loss against Cape Girardeau.

[5] While attending college, the switch hitter began his baseball career, playing with the Indianapolis ABCs and the Detroit Stars.

In 1998, he was inducted into the Indiana State University Hall of Fame, in part for his football talents as a Sycamores fullback, winning All-Indiana Intercollegiate Conference honors in 1934 and 1935.
