"Magic Doors" is the third single from English trip hop band Portishead's third studio album, Third.

The music video for the song is an artistic film by longtime collaborator John Minton.

DJ Green Lantern produced the official remix to the song, known as a Green Lantern remix, that features Linkin Park co-lead vocalist Mike Shinoda and the Los Angeles underground rap duo Styles of Beyond.

Portishead performed the song live on current TV, which is featured as a UK digital download bonus track from their third studio album Third in April 2008.

The videos for "Silence", "Threads" and "Mysterons" were recorded during Portishead's performance at the 2008 Coachella Valley Music and Arts Festival.
