"That Girl" is a song by American R&B singer and songwriter Stevie Wonder. It was the leading single from Wonder's album-era 1982 greatest-hits compilation, Stevie Wonder's Original Musiquarium I, as one of four newer songs from the collection. The song spent nine weeks at number one on the Billboard R&B singles chart, the longest time a Stevie Wonder single spent at the top spot. It also peaked at number four on the Billboard Hot 100 for three consecutive weeks from March 20 to April 3, 1982.
