Ryne Dee Sandberg, nicknamed "Ryno," is a former Major League Baseball second baseman. He played major-league baseball for sixteen years and spent nearly his entire career with the Chicago Cubs. He was named for relief pitcher Ryne Duren and is recognized as one of the best second basemen of his era. Sandberg was elected to the National Baseball Hall of Fame in January 2005; he was formally inducted in ceremonies on July 31, 2005.

Sandberg is currently the third base coach and infield instructor for the Philadelphia Phillies.

Sandberg established himself as a perennial All-Star and Gold Glove candidate, making 10 consecutive All-Star appearances and winning nine consecutive Gold Gloves from 1983 to 1991. His career .989 fielding percentage is a major-league record at second base.

The Cubs, who initially wanted Sandberg to play center field, installed him as their third baseman, and he went on to be one of the top-rated rookies of 1982. However, Sandberg was displaced by Chicago's trade for veteran Ron Cey following the 1982 season, so Sandberg moved to second base, where he became a star.

Sandberg delivered what many traditionalist fans considered a stirring speech at his Hall of Fame induction ceremony in 2005. He thanked the writers who voted for him because it meant that he played the game the way he had been taught it should be played. He spoke several times of respect for the game, and chided a subset of current players who, in his opinion, lack that respect. Specifically, he spoke of how the game needs more than home run hitters, citing that turning a double-play and laying down a sacrifice bunt are weapons many of today's greats don't value. He also made a strong pitch for induction of his former teammate, Andre Dawson, who was ultimately elected to join the Hall in 2010.

Following his Hall of Fame induction, Sandberg had his number 23 retired in a ceremony at Wrigley Field on August 28, 2005, before a Cubs game against the Florida Marlins. He became only the fourth Chicago Cub to have his number retired, following respectively Ernie Banks (#14), Billy Williams (#26), and Ron Santo (#10). Since then, Ferguson Jenkins (#31) and Greg Maddux (also #31) have been retired. Since his retirement, no other Cub had been assigned #23. Sandberg has worn his uniform number 23 in past jobs as a Cubs spring training instructor and Peoria Chiefs manager. He also wore that number during his time with the Iowa Cubs as their manager and as the manager of the Lehigh Valley IronPigs.
