This is a list of some of the records relating to home runs hit in baseball games played in the Major Leagues. Some Major League records are sufficiently notable to have their own page, for example the single-season home run record, the progression of the lifetime home run record, and the members of the 500 home run club. A few other records are kept on separate pages, they are listed below. In the tables below, players and teams denoted in boldface are still actively contributing to the record noted, while (r) denotes a player's rookie season.
