Sheer Terror are an American hardcore punk band from New York City. The band was one of the first to combine elements of heavy metal with a hardcore punk base, pioneering a heavier style of hardcore that would create many bands in the following decades. Formed in late 1984, the band stayed together until 1998, through numerous lineup changes and shifts in musical style. In October 2004, the band reunited for two shows at New York City's CBGB Club.
