In baseball statistics, fielding percentage, also known as fielding average, is a measure that reflects the percentage of times a defensive player properly handles a batted or thrown ball. It is calculated by the sum of putouts and assists, divided by the number of total chances (putouts + assists + errors).^[1]

While a high fielding percentage is regarded as a sign of defensive skill, it is also possible for a player of lesser defensive skill to have a high fielding percentage, as it does not reflect or take into account a player's defensive range;^[2] a player who cannot get to a ball surrenders a hit instead of having an opportunity to make an out or an error.^[3] Conversely, a highly skilled fielder might have a comparatively low fielding percentage by virtue of reaching, and potentially missing, a greater number of balls.

In order to qualify for the league lead in fielding percentage, an infielder or outfielder must appear at the specific position in at least two-thirds of his team's games (games in the outfield are not separated by position).^[4] A catcher must appear in at least half his team's games.^[5] A pitcher must pitch at least one inning for each of his team's scheduled games (however, a pitcher with fewer innings may qualify if they have more total chances and a higher average).^[6] In order to qualify for major league career records for fielding average, a player must appear in 1,000 games at the position; pitchers must have at least 1,500 innings.

The MLB record for team fielding percentage is currently held by the 2013 Baltimore Orioles, with a .99104 fielding percentage.
