Helmut Niedermayr (29 November 1915 – 3 April 1985) was a German racing driver who made one Formula One World Championship appearance, on 3 August 1952. He completed his brief Grand Prix career without scoring a point.
Earlier that year, Niedermayr shared second place at the 24 Hours of Le Mans with Theo Helfrich. Only weeks later, his car left the course during a race at the Grenzlandring and struck spectators, killing at least 13 people and injuring 42.
