The Hamilton Nationals were a Major League Lacrosse (MLL) professional men's field lacrosse team based in Hamilton, Ontario, Canada. They began play in the 2009 season in Toronto, Ontario as the Toronto Nationals, becoming the first-ever Canadian team in MLL history. In 2009, they played their home games at BMO Field, which is also home to Major League Soccer's Toronto FC but moved to the smaller Lamport Stadium for the 2010 season. On February 3, 2011, the Nationals announced that they were relocating to Hamilton, Ontario, and would play their home games at Ron Joyce Stadium on the campus of McMaster University. On 21 November 2013, MLL announced that the team would not participate in the 2014 season, with most of the players being transferred to the expansion Florida Launch.
