3671 Dionysus is a small binary Amor asteroid, orbiting between Earth and the asteroid belt. It was discovered by Carolyn and Gene Shoemaker at Palomar Observatory on 27 May 1984. It is named after Dionysus, the Greek god of wine. Its provisional designation was 1984 KD. It is an outer Earth grazer because its perihelion is just within Earth's orbit.
