Super Bowl X was an American football game between the National Football Conference (NFC) champion Dallas Cowboys and the American Football Conference (AFC) champion Pittsburgh Steelers to decide the National Football League (NFL) champion for the 1975 season. The Steelers defeated the Cowboys by the score of 21–17 to win their second consecutive Super Bowl.

The game was played at the Orange Bowl in Miami, Florida, on January 18, 1976, one of the first major national events of the United States Bicentennial year. Both the pre-game and halftime show celebrated the Bicentennial, while players on both teams wore special patches on their jerseys with the Bicentennial logo.

Super Bowl X featured a contrast of styles between the Steelers and the Cowboys, which were, at the time, the two most popular teams in the league. Pittsburgh, who dominated teams with their "Steel Curtain" defense and running game, finished the regular season with a league best 12–2 record and defeated the Baltimore Colts and the Oakland Raiders in the playoffs. The Cowboys, with their offense and "flex" defense, became the first NFC wild-card team to advance to the Super Bowl after posting a 10-4 regular season record and postseason victories over the Minnesota Vikings and the Los Angeles Rams.

The Super Bowl is the annual championship game of the National Football League (NFL), the highest level of professional American football in the United States, culminating a season that begins in the late summer of the previous calendar year. The Super Bowl uses Roman numerals to identify each game, rather than the year in which it is held. For example, Super Bowl I was played on January 15, 1967, following the 1966 regular season, while the most recent game, Super Bowl XLVI, was played on February 5, 2012, to determine the champion of the 2011 season.

The game was created as part of a merger agreement between the NFL and its then-rival league, the American Football League (AFL). It was agreed that the two leagues' champion teams would play in an AFL–NFL World Championship Game until the merger was to officially begin in 1970. After the merger, each league was redesignated as a "conference", and the game was then played between the conference champions. Currently, the NFC leads the series with 25 wins to 21 wins for the AFC.
