Daniel Edward Barone (born April 24, 1983 in San Jose, CA) is a former Major League Baseball pitcher. Barone attended Sonoma State University, an NCAA Division II school in Rohnert Park, California. He was an 11th-round selection of the Marlins in the 2004 Major League Baseball Draft.

He was called up on August 10, 2007, to become the fifth starting pitcher in the Florida Marlins rotation, filling the empty spot after Florida sent Byung-Hyun Kim to the Arizona Diamondbacks on waivers. He went to the bullpen when the Diamondbacks released Kim, and the Marlins picked him back up. He pitched in 16 games in 2007 (6 as a starter) for the Marlins and became a free agent at the end of the season.

On June 25, 2009, Daniel signed a minor league contract with the Oakland Athletics. He pitched to a 2–8 record with a 6.55 earned run average in 17 games that year between two teams in the A's minor league system and retired after the season. Barone joined the Kansas City T-Bones of the American Association of Independent Professional Baseball and played for them during the 2014 season.

Daniel’s grandfather, Dick Barone, played in 3 major league baseball games as a shortstop for the Pirates in 1960. He had no hits in 6AB.
