In Major League Baseball, the Manager of the Year Award is an honor given annually to the best managers in the American and National Leagues. The award was introduced to baseball in 1983.

The award is voted on by 28 members of the Baseball Writers Association of America. Each places a vote for first, second, and third place among the managers of each league. The formula used to calculate the final scores is Score = 5F + 3S + T, where F is the number of first place votes, S is second place votes, and T is third place votes. The manager with the highest score in each league wins the award.

Bobby Cox became the first manager to win the award in both leagues, with the Toronto Blue Jays in 1985 and the Atlanta Braves in 1991. In 1998, Tony LaRussa became the second, having won the award with the Chicago White Sox in 1983, the Oakland Athletics in 1988 and 1992, and the St. Louis Cardinals in 2002. La Russa has won the most awards with four. Dusty Baker is second with three awards while managing the San Francisco Giants (1993, 1997, 2000).

Five teams remain yet to have a Manager of the Year: Cleveland Indians, Milwaukee Brewers, New York Mets, Tampa Bay Devil Rays, and Arizona Diamondbacks.
