List of baseball players who died during their careers

This is a list of baseball players who died during their careers. While some of these deaths occurred during a game, the majority were the result of accidents off the field, illnesses, acts of violence, or suicide.

Repeated studies have shown that contemporary Major League Baseball players have a greater life expectancy than males in the general U.S. population — about five years more, on average, which is attributed to their superior fitness and healthy lifestyles. The longer the active career, the longer the player lives, on average. This correlation is attributed to the maintenance of fitness and increased wealth.
