Daniel Cooley Uggla (born March 11, 1980) is a Major League Baseball All-Star second baseman for the Florida Marlins. Uggla finished third in the 2006 National League Rookie of the Year voting behind teammate and winner Hanley Ramirez, and Ryan Zimmerman of the Washington Nationals, but won the Players Choice and Sporting News NL ROY awards. Dan also has his own fan club at LandShark Stadium who call themselves "Uggla's Ugglies."

Uggla was born in Louisville, Kentucky, the son of Elizabeth Armistead (née Cooley) and John Carl Uggla. His last name means "owl" in Swedish, and he descends from the untitled branch of an old Swedish noble family. After graduating from Columbia Central High School in Columbia, TN, in 1998, Uggla attended the University of Memphis where after his junior season he was named an All-American by Baseball America, Baseball Weekly, and Collegiate Baseball.

Drafted by the Arizona Diamondbacks in the 11th Round (338th overall) of the 2001 Major League Baseball Draft, Uggla spent five seasons in the Diamondbacks organization, including a year with the short season-advanced team, the Yakima Bears in Yakima, Washington. He amassed a .276 career minor league batting average, .341 on-base percentage, and .443 slugging percentage, to go along with 64 home runs, 311 runs batted in, and 62 stolen bases. Although he was 25 years old, which would make him the same age as many AAA players, and moderately successful in 2005, he never advanced past the AA level.
