Jim Irwin (February 7, 1934 – January 22, 2012) was a longtime sportscaster at WTMJ Radio in Milwaukee, Wisconsin. He is probably best known as having been the radio voice of the Green Bay Packers for 30 years. He worked with former Packer Lionel Aldridge, and was paired for 20 seasons with Super Bowl I hero Max McGee. Irwin also called Milwaukee Brewers baseball, Milwaukee Bucks basketball, and Wisconsin Badgers football and basketball games. He joined the Packers radio broadcasts as a color commentator in 1969 and assumed play by play duties in 1975, a position he held until his retirement after the 1998 season. He was inducted into the Packers Hall of Fame in 2003. Irwin continued to contribute occasionally to WTMJ after he retired.
