Harald Hudak (born 28 January 1957 in Vaihingen an der Enz) is a retired (West) German middle-distance runner who specialized in 1500 metres.
He was one of the runners that set a world record of 14:38.8 minutes in the 4x1500 metres relay in 1977, together with Thomas Wessinghage, Michael Lederer, and Karl Fleschen. He ran 3:40.2 minutes on the second leg.
He finished sixth in 1500 m at the 1979 European Indoor Championships. In 1980, Hudak temporarily became the third-fastest 1500 m runner of all time when he set a personal best of 3:31.96 minutes at a meeting in Koblenz where Steve Ovett set a new world record and Thomas Wessinghage set a new German record. 3:31.96 remained his career best time. In Germany only Thomas Wessinghage has run faster.[1] However, Hudak could not participate in the 1980 Summer Olympics in Moscow due to the West German boycott.
Hudak competed for the sports club Bayer 04 Leverkusen during his active career.
