A Hill To Die Upon is an American blackened death metal band from the Monmouth-Galesburg area of Illinois, formed in 2004 by the brothers Adam and R. Michael Cook. The brothers initially founded the band as hardcore project, but eventually started listening to death and black metal, which led them to transform their band's sound. Over the years, various musicians have filled out the band's lineup, which currently consists of the Cook brothers and Nolan Osmond. Signed to Bombworks Records, A Hill To Die Upon has released four albums - Infinite Titanic Immortal in 2009, Omens in 2011, Holy Despair in 2014, and Via Artis, Via Mortis in 2017 - all to a positive critical reception. In 2013, the band also released a stand-alone single, "Manden Med Leen".

Musically, the band is compared primarily to Behemoth as well as Immortal, Naglfar, and Old Man's Child, all of which the brothers cite as among their major influences.
