Yoshinari Ogawa (小川良成, Ogawa Yoshinari) (born November 2, 1966) is a Japanese retired professional wrestler, best known for his appearances with All Japan Pro Wrestling and Pro Wrestling Noah. He earned the nickname of "Rat Boy" from the English-speaking Puroresu fanbase due to his sneaky, clever in-ring tactics and baiting his opponents into quick pins, as well as the dishevelled, greasy appearance he cultivated during the late-1990s.
