"Amnesia" is a song recorded by Australian band 5 Seconds of Summer, taken from their self-titled debut album 5 Seconds of Summer (2014). The mellow pop rock slow jam was announced as a new single during a live stream by the band on 1 July 2014, and was released to American contemporary hit radio as the third single from the album on 15 July 2014.

A lyric video was produced for the song. Filmed in Los Angeles, it was posted on the official VEVO YouTube channel of the band on 2 July 2014, at midnight, after their live stream. The video, focuses on a bedroom, though in some scenes the members of the band appear in a close up. During the whole video the lyrics are projected in the room or on the members' faces.

A music video was also filmed, in which the band members and some girls and boys play around in several different scenes, diving into a pool fully clothed, playing golf on cars, etc. There are also several close-ups of the band-members singing along to the words of the song throughout the video. There are only 3 girls because they see the watcher/fans as the 4th one. The video is filmed from the 4th girl's perspective.

The video is also the second most viewed by 5 Seconds of Summer. It reached 100 million views on August 11, 2016.
