"So Lonely" is a song by English rock band The Police, released as the third and final single in November 1978 from their debut studio album Outlandos d'Amour (1978), and again in February 1980 as a re-release. The song uses a reggae style, and featured Sting on lead vocals.
"So Lonely" has since been covered by a variety of artists, such as Limbeck and The Militia Group.
The song is known for a famous mondegreen where the title is often misheard as "Sue Lawley", a broadcaster famous as a BBC television newsreader at the time the song was released, and later for presenting Desert Island Discs on BBC Radio 4 from 1988 to 2006.
