Planes Mistaken For Stars (also known as Planes or PMFS) is a punk rock/hardcore punk band formed in Peoria, Illinois in 1997. They have released music on Deep Elm and No Idea Records.

They began as an aggressive yet melodic emo band, all but abandoning the genre before its popularity reached the mainstream. These days Planes has more in common with stoner rock than emo, growing more aggressive and experimental with every record. Lead singer and guitarist Gared O'Donnell started the band with guitarist Matt Bellinger, bassist Aaron Wise, and drummer Mike Ricketts. Shortly after the band self–released a self–titled EP, Wise was replaced by Jamie Drier. At this time Deep Elm offered to repackage and distribute the EP which was re–released in the spring of '99.

In 2000, PMFS took part in a mass migration to Denver, Colorado with more than fifteen friends. After the move, the band recorded their second release for Deep Elm, Knife In The Marathon. In 2001, Planes moved over to Gainesville Florida's No Idea Records to release Fuck With Fire. The next year they released a 7" titled Spearheading The Sin Movement and also made an appearance on Black On Black: A Tribute To Black Flag.

In 2003, Planes saw its second line up change. Jamie Drier left the band and was replaced by Chuck French. Chuck played his first show with Planes on November 2nd, 2003. Later that year, Planes recorded Up In Them Guts with A.J. Mogis, who's most notable work is with Saddle Creek artists Bright Eyes and The Faint. Up In Them Guts was released in the summer of 2004 on No Idea Records. To promote the record, the band took on one of the lenghthiest tour schedules of their career, covering the United States and Europe with a bands such as The Ataris, Cursive, Against Me!, Dillinger Escape Plan, Hot Water Music and High On Fire on six separate, and very diverse tours. They also made festival appearances at Skate And Surf Fest, Strhess Fest, and Hellfest.

Despite rumors of the band signing with legendary metal label Relapse Records, they announced a deal with Abacus Recordings in the fall of 2005 as well as plans to release a new record on 06/06/06.
