Metal Hammer (sometimes MetalHammer) is a monthly heavy metal magazine in the United Kingdom, Ireland and in Germany, Austria, Finland, Spain, Greece, Poland, Hungary, Switzerland, Serbia, and Montenegro by a different publisher. Featuring mainstream and more unusual bands from the wide spectrum of metal music. It is the second-largest selling rock magazine in the UK behind Kerrang! and was often viewed as the more underground magazine, but in recent times has moved towards the mainstream metal market which it originally shunned. In Germany, Metal Hammer has been the market leader since it was launched in 1984.
