Herbert Allen "Rap" Dixon (September 15, 1902 – July 20, 1944) was an American outfielder in Negro league baseball for a number of teams.

Although Dixon began playing in the league in 1922, he joined the semi-pro Harrisburg Giants in 1916 at the age of fourteen.

Dixon was also notable for discovering the Baseball Hall of Famer Leon Day playing in the Baltimore sandlots.

With 20,000 in attendance, Dixon hit one home run in the opener, then two more in the nightcap to help Baltimore salvage a split with the Lincoln Giants.
