"I Don't Remember" is a song by Australian alternative rock band Powderfinger, from the album Dream Days at the Hotel Existence. It made its radio debut on 9 July 2007 on Australian radio stations, and was subsequently released as a single and digital download on 4 August 2007 in Australia, 3 September 2007 in New Zealand, and 13 August 2007 in the United States.

The song was written by Powderfinger lead singer Bernard Fanning, and influenced by bassist John Collins. The riff was then developed by guitarist Ian Haug. The song is about reconciling difficulties and arguments, rather than shifting the blame.

"I Don't Remember" was lauded by some reviewers, who appreciated its energy, while other reviewers were more critical, dubbing it an "advertisement song". The music video also received critical acclaim, especially for the parodies it contained. Despite the reviews, the single charted poorly, reaching number 42 on the ARIA Singles Chart.
