新金属（Nu Metal）属于重金属音乐中的一个分支。最早起源于90年代。

1990年代，一些新派的重金属乐队把重金属乐加入了不同的元素和演绎方式，如加入PUNK或HIP HOP的节奏、DJ混音、MIDI、说唱等，形成了新金属(Nu-Metal)。 而新金属与传统重金属有很多不同之处，如没有或较少吉他独奏部份、新金属乐手不一定像传统重金属乐手般留长发、主唱不一定以死腔或咆哮狂吼唱完整首歌、以较悦耳的旋律贯穿整首歌等等。

Nu metal (also known as nü-metal and aggro-metal) is a form of alternative metal that combines elements of heavy metal music with elements of other music genres such as hip hop, alternative rock, funk and grunge. Nu metal bands have drawn elements and influences from a variety of musical styles, including multiple genres of heavy metal. Nu metal rarely features guitar solos; the genre is heavily syncopated and based on guitar riffs. Many nu metal guitarists use seven-string guitars that are down-tuned to play a heavier sound. DJs occasionally are featured in nu metal to provide instrumentation such as sampling, turntable scratching and electronic backgrounds. Vocal styles in nu metal include singing, rapping, screaming and growling. Nu metal is one of the key genres of the New Wave of American Heavy Metal.
