Peter Edward Rose Sr. (born April 14, 1941), also known by his nickname "Charlie Hustle", is an American former professional baseball player and manager. Rose played in Major League Baseball (MLB) from 1963 to 1986, most prominently as a member of the Cincinnati Reds team known as The Big Red Machine for their dominance of the National League in the 1970s. He also played for the Philadelphia Phillies and the Montreal Expos. During and after his playing career, he served as the manager of the Reds from 1984 to 1989.

Rose was a switch hitter and is the all-time MLB leader in hits (4,256), games played (3,562), at-bats (14,053), singles (3,215), and outs (10,328). He won three World Series, three batting titles, one Most Valuable Player Award, two Gold Gloves, and the Rookie of the Year Award. Rose made 17 All-Star appearances at an unequaled five positions (second baseman, left fielder, right fielder, third baseman, and first baseman). Rose won both of his Gold Gloves when he was an outfielder, in 1969 and 1970.

In August 1989 (his last year as a manager and three years after retiring as a player), Rose was penalized with permanent ineligibility from baseball amidst accusations that he gambled on baseball games while he played for and managed the Reds; the charges of wrongdoing included claims that he bet on his own team. In 1991, the Baseball Hall of Fame formally voted to ban those on the "permanently ineligible" list from induction, after previously excluding such players by informal agreement among voters. After years of public denial, Rose admitted in 2004 that he bet on baseball and on the Reds. The issue of Rose's possible reinstatement and election to the Hall of Fame remains contentious throughout baseball.

In June 2015, ESPN concluded its own investigation of Rose and determined that he had bet on baseball while still a player–manager. The results of the investigation were made public, revealing the records of bets that Rose had made on baseball. U.S. federal authorities had seized the records from one of Rose's associates. Rose is the only person to be placed on the ineligible list by mutual agreement, even though there is no proof he bet against his team.
