"So Lonely" is a song by British rock band the Police, released as the third and final single on 24 November 1978 from their debut studio album Outlandos d'Amour (1978).

Sting said he based the song on Bob Marley's "No Woman, No Cry": "People thrashing out three chords didn't really interest us musically.

I mean let's be honest here, 'So Lonely' was unabashedly culled from 'No Woman No Cry' by Bob Marley & the Wailers.

You're so isolated..."[6] "So Lonely" was released as the third and final single from Outlandos d'Amour in November 1978, following "Roxanne" and "Can't Stand Losing You."

The video for the song depicts the band walking around the streets of Hong Kong and on the subway trains of Tokyo in 1980.
