"I'm Not Okay (I Promise)" is the second single and fifth track from My Chemical Romance's second studio album, Three Cheers for Sweet Revenge. It is often wrongly referred to as their first ever single. It is however, their sixth overall single. It reached #86 on the U.S. Billboard Hot 100, and #19 on the UK Singles Chart. The song also helped expand the band's fan base. The song was re-released in November of 2005. The song is also included in the EA Trax listing for racing game Burnout 3: Takedown. The cover art was redone in live action on the inside of the band's DVD "Life on the Murder Scene".

The song was originally titled "I Promise It's The Last Time".
