Arthur Duncan (born September 25, 1933 in Pasadena, California) is a tap dancer, known for his stint as a performer on The Lawrence Welk Show from 1964 to 1982, which made him the first African-American regular on a variety television program.

On most episodes, Duncan also teamed up with fellow dancers Bobby Burgess and Jack Imel to perform popular dance numbers.
