John W. Harbaugh (born September 23, 1962) is an American football coach who has been the head coach of the Baltimore Ravens of the National Football League (NFL) since 2008. Previously, he coached the defensive backs for the Philadelphia Eagles and served as the Eagles special teams coach for nine years. Harbaugh and his younger brother, former San Francisco 49ers and now University of Michigan head coach Jim Harbaugh, are the first pair of brothers in NFL history to serve as head coaches. Jack Harbaugh, Jim and John's father, served 45 years as a college defensive coach, an assistant coach, and a running backs coach. John and the Ravens beat his brother, Jim, and the 49ers at Super Bowl XLVII in New Orleans on February 3, 2013 by a score of 34-31.
He has led the Ravens to 95 wins (including playoffs) since his tenure began in 2008, fourth most in the NFL over that span, and has surpassed Brian Billick for the most wins by a head coach in Baltimore Ravens franchise history. His 10 playoff wins are the second most by any head coach in the NFL since 2008. Outside winning Super Bowl XLVII, Harbaugh has guided the Ravens to two AFC North division championships and three AFC Championship appearances.
