"#1 Crush" is a song by Garbage, released internationally on the B-side to their debut release "Vow", and in the United Kingdom on the B-side to second single "Subhuman".

In 1996, the track was remixed by Nellee Hooper and Marius de Vries for the soundtrack to Baz Luhrmann's modernised William Shakespeare's Romeo + Juliet movie adaptation. The remix of "#1 Crush" peaked at No. 1 on Billboard's Hot Modern Rock Tracks, where it stayed for four weeks, and as of 2014 is Garbage's sole #1 entry on any US chart. "#1 Crush" was the first of two hit singles from the Romeo + Juliet soundtrack; "Lovefool" by The Cardigans continued the success of the compilation. In 1997, "#1 Crush" was later nominated for Best Song from a Movie at the MTV Movie Awards.

In 2007, the remix of "#1 Crush" was remastered and included on Garbage's greatest hits album Absolute Garbage.

"#1 Crush" was written and recorded between March, 1994 and May, 1995 during sessions between band members Duke Erikson, Shirley Manson, Steve Marker and Butch Vig in either Marker's basement recording studio or at their own Smart Studios in Madison. Manson was concerned that listeners wouldn't realise that the song was about a stalker: "It's about somebody who wasn't quite right. The song however were slightly autobiographical. Everybody's felt obsessive about something or somebody in their life. I've felt crazy about somebody before," she explained, "That feeling - usually when you've split up with somebody - when you're absolutely obsessed with what they are doing. It's all to do with being pathetic".
