The Arizona Cardinals are a professional American Football team based in Tempe, Arizona. They play their home games in Glendale, Arizona. The Cardinals are members of the Western Division (NFC West) of the National Football Conference (NFC) in the National Football League (NFL). The Cardinals were founded in 1898, and are the oldest continuously run professional American football club in the United States.

The team was established in Chicago in 1898 and was a charter member of the NFL in NFL Year1920. Along with the Chicago Bears, the club is one of two franchises still in operation since the leagues founding. The club moved to St. Louis, Missouri, in Cardinals NFL season1960 and played in that city through Cardinals NFL season1987 (sometimes referred to as the "football Cardinals", "Big Red" or "Cardiac Cards" to avoid confusion with the baseball St. Louis Cardinals). Before the 1988 NFL season, the team moved to Tempe, Arizona, an eastern suburb of Phoenix, and played their home games for the next 18 years at Arizona State Universitys Sun Devil Stadium. In nfly2006 the club began playing all home games at the newly constructed University of Phoenix Stadium in the northwestern suburb of Glendale (Glendale, Arizona).

The franchises lone NFL championship game victory came in Cardinals NFL season1947 while they were based in Chicago, and came two decades before the first Super Bowl game was ever played. The clubs other NFL championship occurred in Cardinals NFL season1925, eight years before the league began holding a championship game, and is a controversial title to this day. The much contested title was believed to belong to the Pottsville Maroons but was given to the Cardinals instead in what is called the 1925 NFL Championship controversy. In the six-plus decades since winning the championship in 1947, the Cardinals have qualified for the playoffs only six times and have won only five playoff games, three of which were achieved during their run in the 2008-09 NFL Playoffs (NFL playoffs, 2008-09) in which they reached Super Bowl XLIII. The team has also won only four division titles (nfly1974, nfly1975, nfly2008, and nfly2009) since their 1947–1948 NFL championship game appearances. In addition, the club has won one NFC Championship Game in 2008.

The Cardinals conduct their annual summer training camp at Northern Arizona University in Flagstaff.
