Martin Jellinghaus

Martin Jellinghaus (born 26 October 1944) is a retired West German former athlete who competed mainly in the 400 metres.

He competed for West Germany in the 1968 Summer Olympics held in Mexico City, Mexico in the 4×400 metre relay. He won the bronze medal with his teammates Helmar Müller, Manfred Kinder and Gerhard Hennige. During the games, along with the Australian sprinter Peter Norman, he wore Olympic Project for Human Rights badges to show support for the suspended American sprinters Tommie Smith and John Carlos, the two gold and bronze medalists in the men's 200-meter race, who took their places on the podium for the medal ceremony barefooted and wearing civil rights badges, lowering their heads and each defiantly raising a black-gloved fist as The Star-Spangled Banner was played.
