The '''Home Run Derby''' is an annual home run hitting competition in [[Major League Baseball]] (MLB) customarily held the day before the [[Major League Baseball All-Star Game|MLB All-Star Game]], which places the contest on a Monday in July. In the context of the competition a "home run" consists of hitting a baseball in fair territory out of the playing field on the fly. It differs from a [[home run]] hit during legal gameplay in that the batter is not competing against a pitcher and a defensive team attempting to make an [[out (baseball)|out]]. In the Home Run Derby, all pitches are purposefully thrown slowly and at a closer range than the official {{convert|60|ft|6|in|m}} distance, usually by a [[Coach (baseball)|coach]] behind a pitching screen. In addition, like batting practice, the batter remains in the batter's box after each swing and does not run, nor circle the bases to score a [[run (baseball)|run]]. In 2023, [[Julio Rodríguez]] set the single-round home run record with 41 homers, topping [[Vladimir Guerrero Jr.]]'s 40 home runs in 2019.

The batter also does not have to conform to the usual league uniform standards, and as all pitches are tossed in the [[strike zone]] without any threat of [[beanball]]s, may choose to wear a regular [[baseball cap]] instead of a [[batting helmet]]. As the event traditionally takes place at [[sunset]] where the sun is of no factor to the batter, they can choose to wear their hat casually and backwards.

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.

[[T-Mobile]] has been the title sponsor of the Home Run Derby since 2021.
