Major League Baseball (MLB) honors its best rookies with a Rookie of the Month Award for one player in the American League (AL) and one in the National League (NL) during each month of the regular season.
These awards have been issued since 2001, with players at all positions eligible.
The below tables list the winners in each league since the award was established in 2001.
In two instances, the award has been shared by players for the same month: Josh Johnson and Dan Uggla for June 2006 in the National League (NL); and Ben Revere and Jemile Weeks for June 2011 in the American League (AL).
Out of a possible six months during a player's rookie season, the most times a player has been named Rookie of the Month is four, achieved by Ichiro Suzuki (2001, AL), Mike Trout (2012, AL) and Aaron Judge (2017, AL).
