Infant Annihilator are an English-American deathcore band formed in Hull, East Riding of Yorkshire in 2012 by drummer Aaron Kitcher and guitarist Eddie Pickard. The band is noted for its technical, eclectic and extreme musical style; parodistic and satirically graphic lyrical content and shock humour; and music videos that feature ribald themes.

Their debut album The Palpable Leprosy of Pollution, which is the only album to feature American vocalist Dan Watson, was released in late 2012. After replacing their vocalist with Massachusetts-native Dickie Allen, their second album The Elysian Grandeval Galèriarch was recorded and mixed by Jesse Kirkbride at his home studio Kirkbride Recordings and was released in 2016. Their third album, The Battle of Yaldabaoth, was released on 11 September 2019.

Infant Annihilator were described by the Hysteria Magazine as an Internet band and even though they have stated that touring is a possibility, they have performed only as a studio project so far.
