Barry Alvarez (born December 30, 1946) is the coach of University of Wisconsin's college football team.

Alvarez was born in the small mining town of Langeloth, Pennsylvania near Burgettstown. In high school, Alvarez won all-conference recognition and played in the Big 33 All-Star Game, an invitation-only exhibition game for Pennsylvania’s top seniors.

Alvarez attended the University of Nebraska on a football scholarship graduating in 1969. After college, he coached high school football in Nebraska and Iowa.

After coaching high school football, Alvarez began his college coaching career under legendary Iowa head coach Hayden Fry in 1979. He later became as assistant coach at Notre Dame under Lou Holtz. In 1990, Alvarez was named head coach of the Wisconsin Badgers.

Since becoming head coach of the Badgers, he has become the winningest coach in school history, leading the Badgers to three Big Ten championships and three Rose Bowl victories, and has a bowl record of 7-2.

Alvarez replaced Pat Richter as Athletic Director at the University of Wisconsin in 2004. Alvarez is one of only two people (along with Watson Brown of the University of Alabama at Birmingham) that act as head football coach and Athletic Director at a Division 1 school.

In 2000, Alvarez and his wife Cindy endowed a $250,000 football scholarship at the university.

In 1994, Babcock Hall, which houses the UW-Madison's dairy school, developed an ice cream flavor called "Berry Alvarez" in honor of the coach. It's flavor was a mixture of raspberry, strawberry and blueberry.
