Alfred was born in Downey, California. He was raised in the town of Lynwood, California. He is the only child of Nick Louis Yankovic (June 4, 1917 – April 9, 2004) and Mary Elizabeth Yankovic (née Vivalda; February 7, 1923 – April 9, 2004). His father was born in Kansas City, Kansas, of Yugoslavian ancestry, and began living in California after serving during World War II; he believed "the key to success" was "doing for a living whatever makes you happy" and often reminded his son of this philosophy. Nick Yankovic married Mary Elizabeth Vivalda in 1949. Mary, who was of Italian and English descent, and had come to California from Kentucky, gave birth to Alfred ten years later.
