Mike Douglas, born Michael Delaney Dowd, Jr. (August 11, 1925 – August 11, 2006), was an American entertainer.

Douglas was born in Chicago, Illinois, and began singing as a choirboy. By his teens he was working as a singer on a Lake Michigan dinner cruise ship. After serving briefly in the United States Navy near the end of World War II and as a "staff singer" for WMAQ-TV in Chicago, he moved to Los Angeles. There he became a vocalist in the big band of Kay Kyser, with whom he was featured on two notable hits, "Ole Buttermilk Sky" in 1946 and "The Old Lamplighter" the following year. Kyser was responsible for giving him his show business name, and he remained part of Kyser's band until Kyser retired from show business in 1951.

In 1950, he provided the singing voice of Prince Charming in Walt Disney's Cinderella.
