The Buffalo Bills are a professional football team based in Buffalo, New York. They are members of the East Division of the American Football Conference (AFC) in the National Football League (NFL). They play their home games in the suburb of Orchard Park, and since the 2008 NFL season, play one home game per season and three pre-season games in Toronto as part of the 5-year Bills Toronto Series. The Bills began competitive play in 1960 as a charter member of the American Football League and joined the NFL as part of the AFL-NFL merger in 1970.

The Bills won two consecutive American Football League titles in 1964 and 1965, but the club has not won a league championship since then. Buffalo is also the only team to win four consecutive American Football Conference Championships, the only team in either conference to play in four consecutive Super Bowl games, and the only team ever to lose those four consecutive Super Bowls, consequently to the NFC East.

The Bills were named as the result of the winning entry in a local contest by Michael Doucas, which named the team after the AAFC Buffalo Bills, a previous football franchise from the All-America Football Conference that merged with the Cleveland Browns in 1950. That team was named after the historic "Buffalo Bill" Cody. The Bills' cheerleaders are known as the Buffalo Jills. The official mascot is Billy Buffalo; Cody is not used in the team's iconography at all.

James Edward Kelly (born February 14, 1960) is a former American football quarterback in the NFL for the Buffalo Bills and the USFL's Houston Gamblers.

Kelly was the third quarterback drafted in the 1983 NFL Draft, the same draft class where John Elway was first overall. Employing the K-Gun offense, known for its hurry up shotgun formations, Kelly lead one of the great NFL scoring juggernauts in the Buffalo Bills. Kelly led the Bills to four consecutive Super Bowls, from 1991 to 1994, but lost all four. In 2002, in his first year of eligibility, he was inducted into the Pro Football Hall of Fame.

Jim Kelly's number 12 is the only number ever retired in Buffalo Bills history. In 2009, Kelly was elected to the Buffalo Bills 50th Season All-time Team.

Kelly grew up in the small town of East Brady, Pennsylvania, about 55 miles northeast of Pittsburgh. He was a standout at East Brady High School, where during his high school career he won all-state honors after passing for 3,915 yards and 44 touchdowns. After his senior year, Kelly played in the Big 33 Football Classic.

William Frederick "Buffalo Bill" Cody (February 26, 1846 – January 10, 1917) was an American soldier, bison hunter and showman. He was born in the Iowa Territory (now the U.S. state of Iowa), in Le Claire but lived several years in Canada before his family moved to the Kansas Territory. Buffalo Bill received the Medal of Honor in 1872 for service to the US Army as a scout. One of the most colorful figures of the American Old West, Buffalo Bill became famous for the shows he organized with cowboy themes, which he toured in Great Britain and Europe as well as the United States.

William Frederick Cody ("Buffalo Bill") got his nickname after the American Civil War when he had a contract to supply Kansas Pacific Railroad workers with buffalo meat. Cody earned the nickname by killing 4,280 American bison (commonly known as buffalo) in eighteen months, (1867–1868).Bill Comstock also had the nickname. Cody and Comstock competed in a buffalo-shooting match over the exclusive right to use the name, which Cody won by killing 69 bison to Comstock's 48.
