Aaron John Boone (born March 9, 1973, in La Mesa, California) is a Major League Baseball infielder for the Houston Astros. He previously played for the Florida Marlins, Cincinnati Reds, New York Yankees, Cleveland Indians, and Washington Nationals.

Boone played baseball for the University of Southern California.

On the last day of the 1998 season, the Reds helped him make baseball trivia history by starting the only infield ever composed of two sets of brothers: first baseman Stephen Larkin, second baseman Bret Boone, shortstop Barry Larkin, and third baseman Aaron Boone.
