McCartney II is the second solo studio album by the English musician Paul McCartney, released on 16 May 1980. It was recorded by McCartney at his home studio in the summer of 1979, shortly before the dissolution of his band Wings in 1981. Like his debut solo studio album, McCartney (1970), he performed all the instruments himself. It yielded three singles: "Coming Up", "Waterfalls", and "Temporary Secretary".

The album was a significant departure for McCartney, as much of it relies heavily on synthesizers and studio experimentation, while its music style embraces new wave and elements of electronica. It was initially released to largely unfavourable reviews by critics, though retrospective reception has been more positive and the album has become a cult favourite. In 2011, an expanded edition of McCartney II was issued with over a dozen bonus tracks. In 2020, the album was succeeded by McCartney III. In 2022, the trilogy was reissued in the McCartney I II III box set.
