Frank Joseph Ortenzio Jr. (born February 24, 1951) is an American former Major League Baseball first baseman. He played nine games for the Kansas City Royals in 1973. He also played two seasons (1979 and 1980) in Japan for the Nankai Hawks.

During his time with the Nankai Hawks, he was given the registered name, "Ohtenjoh (王天上)", which translates into the king above heaven. You would see this on scoreboards and in the newspaper. Normally foreign players in Japan are given names in katakana, but because his last name appeared close to Japanese sounds, the team decided to give him a kanji pictograph name.^{[citation needed]}
