The Home Run Derby is an annual home run hitting contest in Major League Baseball (MLB) customarily held the day before the MLB All-Star Game, which places the contest on a Monday in July. Since the inaugural derby in 1985, the event has seen several rule changes, evolving from a short outs-based competition, to multiple rounds, and eventually a bracket-style timed event. It is currently sponsored by T-Mobile, a wireless cellphone company.

The event has grown significantly from its roots in the 1980s, when it was not televised. Prior to 1991, the Home Run Derby was structured as a two-inning event with each player receiving five outs per inning, allowing for the possibility of ties. It is now one of the most-watched events broadcast on ESPN.

In 2000, a "match play"-style format was instituted for the second round. The player with the most home runs in the first round faced the player with the least among the four qualifying players, as did the players with the second- and third-most totals. The contestant who won each matchup advanced to the finals. This format was discontinued after the 2003 competition.

The field of players selected currently consists of four American League players and four National League players. The first Derby in 1985 featured five from each league, and the 1986 and 1987 events featured three and two players from each league, respectively. In 1996, the field was again expanded to ten players, five from each league (though in 1997, the AL had six contestants to the NL's four).

In 2000, the field reverted to the current four-player-per-league format. The only exception was 2005, when Major League Baseball changed the selection criteria with eight players representing their home countries rather than their respective leagues. The change was believed to be in promotion of the inaugural World Baseball Classic, played in March 2006. In 2006, the selection of four players from each league resumed. In 2011, the format was revised so that team captains selected the individual sides.
