James Chester Arthur Hefner Jr. (August 2, 1913 – May 2, 1988) was an American professional baseball center fielder in the Negro leagues.

[5] Heffner was born in Transylvania County, North Carolina on August 2, 1913, the son of James Chester Arthur and Mary Hefner (né Davis).

[6] He made his Negro Major leagues debut on April 25, 1948 with the New York Black Yankees.

[7][8] In February 1949, following the disbanding of the Yankees (itself part of the larger Negro league contraction necessitated by the exodus of star players to the recently integrated Major Leagues), Heffner was initially drafted by the Birmingham Black Barons,[9] but then acquired by Philadelphia prior to the start of the regular season.

[10] Following his baseball career, Hefner was employed by DuPont and served as a deacon in the Bethel "A" Baptist Church in Brevard.
