Redmond, 41, was reportedly the first person Marlins' front office personnel interviewed after Ozzie Guillen was fired Oct. 23. He will be making the move from managing Class A Dunedin in the Toronto organization to managing in the major leagues.
Redmond played seven of his 13 major-league seasons with the Marlins. He was the back-up catcher on the team when it won the World Series in 2003. He also played for Minnesota and ended his playing career in Cleveland in 2010.
He will be the Marlins' 13th full-time manager and fourth person to lead the team since Fredi Gonzalez was fired in 2010. Edwin Rodriguez managed the team in 2010-2011, with Jack McKeon taking over for the last 90 games of the 2011 season. Guillen lasted one season, in which Miami went 69-93.
