Ernst Müller (born 16 May 1954) is a German boxer.
He competed for West Germany in the men's light welterweight event at the 1976 Summer Olympics.
He was also the most probable West German runner-up for the 1980 Summer Olympics, but the West German government decided to join the U.S.-imposed boycott, so Müller missed the event together with the rest of the FRG Olympic squad.
