Nine-pound Hammer is an American cowpunk band. They were formed in 1985 by vocalist Scott Luallen and guitarist Blaine Cartwright in their hometown of Owensboro, Kentucky. They experienced their initial success with Crypt Records.

Nine-pound Hammer was one of the first rural hardcore punk bands to substantially incorporate rural blue collar motifs into the minimalistic hardcore sound. Their lyrics (suggestive of outlaw country) featured themes such as alcoholism, rural poverty, and violence, and included references and homages to the likes of Jesco White and Dale Earnhardt. In contrast, most of the urban, experimental cowpunk bands of 1970s/80s Los Angeles and the UK were roots rock, folk rock or New Wave bands incorporating country music instruments and influences as a secondary (sometimes temporary) aspect of their sound.

Following the breakup of the band in 1997, guitarist Blaine Cartwright formed the band Nashville Pussy, which shares many of Nine-pound Hammer's musical and lyrical conventions with the addition of a lead guitarist and a more hard rock/Southern rock-focused format.
