Franklin E. Wren (born March 17, 1958, at St. Petersburg, Florida) is an American front office executive in Major League Baseball. Since the end of the 2007 baseball season, he has been the general manager of the Atlanta Braves
Wren attended St. Petersburg Junior College and signed with the Montreal Expos as an outfielder in 1977. In five minor league seasons, he batted .259 and peaked with a 38-game trial with the Double-A Memphis Chicks in 1980. He joined the Montreal front office as assistant director of scouting in 1987.
In September of 1991, Wren's boss, Expo GM Dave Dombrowski, accepted the position of general manager of the Florida Marlins, a National League expansion franchise set to begin play in 1993. Wren followed Dombrowski to the Marlins as the club's assistant general manager. He was promoted to vice president in 1996. In 1997, a veteran-laden Marlin club won the franchise's first World Series championship. The following year, in 1998, owner H. Wayne Huizenga would order his front office to divest the team of its high-priced veterans and the Marlins spiraled into the basement of the National League East Division. Nevertheless, Dombrowski, his front office and his farm system were considered among the best in baseball.
