Master's Hammer are a black metal band from the Czech Republic. They were founded in 1987 and produced several demos, before releasing their debut album Ritual in 1991, which sold more than 25,000 copies in the Czech Republic according to the band. Two years later they completed The Jilemnice Occultist (often misspelt as The Filemnice Occultist due to a typo on the booklet).

Their third album (Šlágry in 1995) was a drift away from the previous work incorporating many styles outside the metal genre, and the band announced "that Šlágry II and a forthcoming CD-ROM will rely more on professional opera singers and orchestra players", although this following album was never released.
