The Baltimore Stallions were a Canadian Football League team based in Baltimore, Maryland, in the United States, which played the 1994 and 1995 seasons. They were the most successful American team in the CFL's southern expansion into the United States, and by at least one account, the most winning expansion team in North American professional sports history at the time. They had winning records in each season, and in both years advanced to the championship game. In 1995, they became the only American franchise to win the Grey Cup.

The Canadian Football League is a professional sports league in Canada. The CFL is the highest level of competition in Canadian football. The league consists of nine teams, each located in a city in Canada. They are divided into two divisions: four teams in the East Division and five teams in the West Division. As of 2024, it features a 21-week regular season in which each team plays 18 games with three bye weeks. This season traditionally runs from mid-June to early November. Following the regular season, six teams compete in the league's three-week playoffs, which culminate in the Grey Cup championship game in late November. The Grey Cup is one of Canada's largest annual sports and television events. The CFL was officially named on January 19, 1958, upon the merger between the Interprovincial Rugby Football Union or "Big Four" and the Western Interprovincial Football Union.
