"My Father My King" is a song by Scottish post-rock band Mogwai, which was released as a single in October 2001. Over 20 minutes long, and billed as a companion piece to the album Rock Action, a sticker on the cover of the single describes it as "two parts serenity and one part death metal". The song is regularly used to end Mogwai concerts – most recently, in 2015, it was the finale of all six of the band's 20th anniversary shows – and was often extended in length.
