James John Langer (born May 16, 1948) is a former American football center who played for the National Football League's Miami Dolphins and Minnesota Vikings. He is considered one of the greatest NFL centers of all time and a hardworking and quick blocker. Langer was elected to the Pro Football Hall of Fame in 1987, one of only three Dolphins players to be elected to the Hall of Fame in their first year of eligibility (Dan Marino, Paul Warfield).
Langer became the starter at center in the 1972 season and played in 141 consecutive games over 8 seasons until a knee injury ended his playing days with Miami nine games into the 1979 season. Langer was traded to the Minnesota Vikings prior to the 1980 season, playing 2 seasons with the Vikings before retiring after the 1981 campaign.
During a 6-year stretch in the mid-1970s, Langer was named First-team All-Pro 4 times 1974-1977, and Second-team Team All-Pro twice, in 1973 and 1978. He also appeared in the Pro Bowl each of those seasons. Langer played in three Super Bowls with the Dolphins.
The Jim Langer Award is presented to the nation's top Division II lineman each year in his honor.
