Kathryn Elizabeth "Kate" Smith (May 1, 1907 – June 17, 1986) was an American singer, best known for her rendition of Irving Berlin's "God Bless America". Smith had a radio, TV and recording career spanning five decades, reaching its most-remembered zenith in the 1940s.

Her musical career began in earnest when she was discovered by Columbia Records vice president Ted Collins in 1930, who became her longtime partner and manager and who put her on the radio in 1931. She sang the controversial top twenty song of 1931, "That's Why Darkies Were Born". She starred in the 1932 movie Hello Everybody!, with co-stars Randolph Scott and Sally Blane, and in the 1943 wartime picture This is the Army she sang "God Bless America". Irving Berlin wrote the song in 1918.

Kate began making records in 1926; among her biggest hits were "River, Stay 'Way From My Door" (1931), "The Woodpecker Song" (1940), "The White Cliffs of Dover" (1941), "Rose O'Day" (1941), "I Don't Want to Walk Without You" (1942), "There Goes That Song Again" (1944), "Seems Like Old Times" (1946), and "Now Is the Hour" (1947). Her theme song was "When the Moon Comes Over the Mountain", the lyrics of which she helped write. She greeted audiences with "Hello, everybody!" and signed off with "Thanks for listenin'."
