Michael George Holmgren (born June 15, 1948 in San Francisco, California) is a former American high school, collegiate and Professional Football coach. He served as the head coach of the Green Bay Packers from 1992 to 1998, and the Seattle Seahawks from 1999 to 2008. Prior to his career in the National Football League, Holmgren coached football at the high school and collegiate levels. He is noted for his role in molding quarterbacks such as Joe Montana, Steve Young, Brett Favre and Matt Hasselbeck during his tenures in San Francisco, Green Bay and Seattle. Under Holmgren's leadership and play calling the Green Bay Packers were consistent winners; and, he became known as one of the best coaches in the NFL, leading them to their twelfth league championship in Super Bowl XXXI. The Seahawks also became an annual playoff team under Holmgren and went to the franchise's first Super Bowl in 2005.

Holmgren started out as a Tight End before becoming a standout quarterback at San Francisco's Lincoln High School, where he was named "Prep Athlete of the Year" in 1965 and graduated in 1966. He continued his playing career as a Quarterback at University of Southern California, from 1966-69. As a sophomore he was on USC's national championship team of 1967, and graduated with a Bachelor of Science degree in 1970. He played behind starter Steve Sogge in 1967–68, and a knee injury put him behind sophomore Jimmy Jones in 1969. Although a back-up, Holmgren was drafted by the St. Louis Cardinals in the eighth round (201st overall) of the 1970 NFL draft and went to camp with both the Cardinals and the New York Jets that year.
