"I Miss You" is a song by American rock band Blink-182, released on February 2, 2004, as the second single from the group's self-titled fifth studio album (2003). Co-written by guitarist Tom DeLonge and bassist Mark Hoppus, they employed a method of writing separately and bringing their two verses together later. The song, produced entirely acoustic, features an acoustic electric bass, a cello, and a brushstroked drum loop. The song was inspired by The Cure song "The Lovecats" and contains references to The Nightmare Before Christmas (1993).
The song peaked at number one on the US Billboard Modern Rock Tracks chart and peaked at number 42 on the Billboard Hot 100. Although "All the Small Things" had slightly more radio airplay, "I Miss You" sold more copies, earning gold certification for selling over 500,000 copies. In the United Kingdom, the song was a national top 10 hit on the UK Singles Chart, peaking at number eight.
