Multiple major sports championship seasons


In the history of North American major professional sports league championships a city/metropolitan area has been home to multiple championships in a season seventeen times, most recently in 2018-2019, when the Boston Red Sox and Patriots won their respective leagues, in October 2018 and February 2019. Only Detroit has been host to more than two major league championship teams in a season.
Philadelphia is the only city to have all four major sports teams play in their respective championship game or series in the same season, though only one of the four actually won the championship.
Championships are said to be for the same season if they occur within 12 months of each other.
