All-Star Game Sites, as of 2016

Tonight, the Major League Baseball All-Star Game will be held at Petco Park in San Diego.

The MLB ASG was previously held in San Diego in 1978 and 1992, both times at the old stadium. (It was San Diego Stadium from 1967 to 1980, Jack Murphy Stadium from 1980 to 1997, and has been Qualcomm Stadium ever since.)

The following is a list of All-Star Games held in the various major league cities, including MLB, the National Football League (the Pro Bowl), the National Basketball Association, the National Hockey League, Major League Soccer, the Women's NBA, and defunct leagues like the American Football League, the American Basketball Association and the World Hockey Association. (The old North American Soccer League, not to be confused with the current one, never held an All-Star Game.)
