Jo Elizabeth Stafford (born November 12, 1917) was an American pop singer whose career spanned the late 1930s through the early 1960s. Stafford is greatly admired for the purity of her voice and is considered one of the most versatile vocalists of the era.

She is also considered a pioneer of modern musical parody, having won a Grammy Award for Best Comedy Album in 1961 (with husband Paul Weston) for their album "Jonathan and Darlene Edwards in Paris."
