"It Wasn't Me" is the first single from Jamaican reggae musician Shaggy's fifth studio album, Hot Shot (2000). The song features vocals from Rikrok. The lyrics of the song depict one man (Rikrok) asking his friend (Shaggy) what to do after his girlfriend caught him cheating on her with "the girl next door". His friend's advice is to deny everything, despite clear evidence to the contrary, with the phrase "It wasn't me." "It Wasn't Me" was released to contemporary hit radio on 7 November 2000 and has been regarded as Shaggy's breakthrough in the pop market. It is his highest-charting song to date, topping the charts in Australia, Austria, Flanders, France, Ireland, the Netherlands, Poland, the United Kingdom, and the United States. It was the best-selling single of 2001 in the UK, selling over 1.15 million copies that year and over 1.42 million as of 2017.
The song was inspired by a bit called "No Loyal Men," performed by Eddie Murphy in his comedy special Raw (1987). In an interview in February 2016, Shaggy acknowledged similarities with the War song "Smile Happy". The connection is further supported by Liam Payne's debut single of 2017, "Strip That Down", itself based on "It Wasn't Me", which credited both Shaggy (as Orville Burrell) and members of War as co-songwriters. The clean version of the song replaces the lyric "Picture this: we were both butt-naked banging on the bathroom floor" with "Picture this: we were both caught making love on the bathroom floor" and "Saw me banging on the sofa" with "Saw me kissing on the sofa".
