Masahiko Harada (?? ??, Harada Masahiko) (born 9 May 1968) is a Japanese former ski jumper.
He is best remembered for a meltdown at the 1994 Winter Olympics in Lillehammer, which cost the Japanese national team a victory, and his subsequent redemption at the 1998 Winter Olympics in Nagano; the latter of which led to him being affectionately called "Happy Harada".
