Ignorance is the debut studio album by American thrash metal band Sacred Reich. It was released on October 13, 1987, by Metal Blade Records, and was followed up by the 1988 EP, Surf Nicaragua. The album was co-produced by the band and Bill Metoyer, who had previously engineered most of Slayer's early work. Metal Blade reissued the album and released a 30th anniversary version of it with its original artwork on September 8, 2017, with LP and Digipak CD versions being available. The album's cover art depicts a blind-folded prisoner superimposed over the United States flag, which Metal Paths regarded as "a provocative sign of resistance against the Ronald Reagan administration and its actions." The album cover was initially different but was changed due to the label seeing it as "too punk-looking." In August 2014, Revolver placed Ignorance on its "14 Thrash Albums You Need to Own" list.
