Bob Casey (April 11, 1925 - March 27, 2005) was the only public-address announcer in Minnesota Twins history until 2005. He started announcing Twins games when the franchise moved to Minnesota from Washington, D.C., in 1961.

Casey worked 44 seasons and more than 3,000 games for the Twins. He was inducted into the Twins' Hall of Fame in 2003.

Prior to working for the Twins, Casey served as the announcer of the Minneapolis Millers, a Triple-A team in the old American Association, for 10 years. He also worked for the Minneapolis Lakers and the Minnesota Vikings during his career.
