Haunting the Chapel is an extended play (EP) released by American thrash metal band Slayer in 1984 through Metal Blade and Enigma Records. Slayer's debut album Show No Mercy became Metal Blade's highest-selling, leading to producer Brian Slagel wanting to release an EP. Recorded in Hollywood, the recording process proved difficult when recording drums in a studio without carpet, although it resulted in drummer Dave Lombardo meeting Gene Hoglan who was to become an influence in his drumming style and speed. It was during the recording of this session that Lombardo first had the double bass added to his kit. Hoglan, working for Slayer at the time, sat at the kit and played a double bass for the first time. Lombardo was impressed and although Hoglan never gave him lessons, he did give him tips regarding the use of the double kick drum.

The songs "Captor of Sin" and "Chemical Warfare" were regularly featured on the band's live set list. "Chemical Warfare" appears in Guitar Hero: Warriors of Rock. Recording Slayer's previous album, Show No Mercy, had sold over 40,000 copies worldwide and the band were performing the songs "Chemical Warfare" and "Captor of Sin" live, which made producer Brian Slagel want to release an EP. The album was recorded in Hollywood with sound engineer Bill Metoyer, in a studio with no carpet which was a problem while recording the drums. Slagel was acting as executive producer. Metoyer is Christian and the lyrics from Show No Mercy did not bother him. However, the first words Araya sang when recording Haunting the Chapel were "The holy cross, symbol of lies, intimidates the lives of Christian born", and other anti-religious lyrics; Metoyer thought he would go to Hell for his part in recording the lyrics. These lyrical themes were inspired by the band Venom, who influenced King and was also into the Satanic image. Slayer drummer Dave Lombardo set his drum kit on the concrete and the kit went "all over the place" while playing. Lombardo asked Gene Hoglan to hold his kit together, while recording "Chemical Warfare", with Hoglan thinking, "I hope he does this in one
