Hideo Hiraoka (平岡英郎, Hiraoka Hideo, 30 April 1971, Tochigi) is a Japanese professional drifting driver, currently competing in the D1 Grand Prix series for Team Orange and Yuke’s.

Like many of the drivers in the D1GP he is the owner of his own tuning shop called Proshop Rapid, and so has worked on many of his cars himself.

In 2006, he went back to the Nissan Silvia S15, sponsored by Wisesquare (previously driven by Makoto Sezaki) with which he had much success, getting his first win with that machine, and again, driving Team M.O.V.E.

's second S15 (which Kazama used for D1GP 2006 Silverstone and D1GP 2006 Las Vegas) while his friend and teammate at the time, Katsuhiro Ueo drove the first S15, which was Kazama's 2005 championship car, and to become the fourth member of Team Orange, driving Nobushige Kumakubo's 2006 championship winning Subaru Impreza.

So far he has been doing well adapting to the new car, as he has done so often before, though he had a large accident at the Tokyo Drift exhibition match in early 2008.
