Namath was born and raised in Beaver Falls, Pennsylvania (30 miles (50 km) northwest of Pittsburgh), and grew up in its Lower End neighborhood. He is the son of Catholic parents, Rose (nee Juhasz) and Janos "John" Andrew Namath, a steelworker. His parents were of Hungarian descent. His Hungarian-born grandfather, Andras "Andrew" Nemeth, known as "A.J." to his family and friends, came to Ellis Island on the steamer Pannonia in 1911, and worked in the coal and steel industries of the greater Pittsburgh area.

Despite suffering a nagging knee injury in the fourth game of his senior year at Alabama, Namath limped through the undefeated regular season to the Orange Bowl. He was a first-round draft selection by both the NFL and the upstart AFL. The two competing leagues were at the height of their bidding war, and held their respective drafts on the same day: November 28, 1964. The cartilage damage to Namath's right knee later designated him class 4-F for the military draft, a deferment from service during the Vietnam War.  The St. Louis Cardinals selected Namath 12th overall in the NFL Draft, while the Jets selected him with the first overall pick of the AFL draft. When meeting with executives of the Cardinals, Namath's salary request was $200,000 and a new Lincoln Continental. While initially appalled at Namath's requests, the Cardinals told Namath they would agree to his requests, but only if he would sign before the Orange Bowl, which would've made Namath ineligible to play in the game. The day after the Orange Bowl, Namath elected to sign with the Jets, which were under the direction of owner Sonny Werblin, for a salary of US$427,000 over three years (a pro football record at the time). Offensive tackle Sherman Plunkett came up with the nickname "Broadway Joe" in 1965, following Namath's appearance on the cover of Sports Illustrated in July.  In Namath's rookie season the 1965 Jets were winless in their first six games with him splitting time with second-year quarterback Mike Taliaferro. With Namath starting full-time they won five of the last eight of a fourteen-game season and Namath was named the AFL Rookie of the year. He became the first professional quarterback to pass for 4,000 yards in a season when he threw for 4,007 yards in (1967), a record broken by Dan Fouts in a 16-game season in 1979 (4,082). Although Namath was plagued with knee injuries through much of his career and underwent four pioneering knee operations by Dr. James A. Nicholas, he was an AFL All-Star in 1965, 1967, 1968, and 1969. On some occasions, Namath had to have his knee drained at halftime so he could finish a game. Later in life, long after he left football, he underwent knee replacement surgery on both legs.  In the 1968 AFL title game, Namath threw three touchdown passes to lead New York to a 27-23 win over the defending AFL champion Oakland Raiders. His performance in the 1968 season earned him the Hickok Belt as top professional athlete of the year. He was an AFC-NFC Pro Bowler in 1972, is a member of the Jets' and the American Football League's All-Time Team, and was elected to the Hall of Fame in 1985.
