This is a list of the top 500 Major League Baseball homerun hitters. In the sport of baseball, a homerun is a hit in which the batter scores by circling all the bases and reaching home plate in one play, without the benefit of a fielding error. This can be accomplished both by hitting the ball out of play while it is still in fair territory (a conventional home run), or by an inside the park home run. Barry Bonds holds the Major League Baseball home run record with 762. He passed Hank Aaron, who is currently second with 755, on August 7, 2007.
