力量金属（Power Metal）为重金属音乐的一种分支。力量金属大可再分为美国派别和欧洲派别。

当英国重金属新浪潮中铁娘子和犹大圣徒的卓越成功，美国力量金属在1980年代冒起。Metal Church、Savatage、Helstar、Jag Panzer、Manowar及近似的乐团，他们演绎出来的风格带有鞭笞金属的味道。有人认为现代的美国团队如Iced Earth和 Nevermore就是该类型音乐的佼佼者，但始终被欧洲力量金属和敲击金属所盖过，并意味着美国力量金属的没落。另外又有人认为美国力量金属借由鞭笞复兴再度被重视。

Power metal is a subgenre of heavy metal combining characteristics of traditional metal with speed metal, often within symphonic context. Generally, power metal is characterized by a more uplifting sound, instead of the heaviness and dissonance prevalent in styles such as doom metal and death metal. Power metal bands usually have anthem-like songs with fantasy-based subject matter and strong choruses, thus creating a theatrical, dramatic and emotionally "powerful" sound. The term was first used in the middle of the 1980s and refers to two different but related styles: the first pioneered and largely practiced in North America with a harder sound similar to speed metal, and a later more widespread and popular style based in Europe (especially Scandinavia, Germany, Greece and Italy), South America (especially Brazil and Argentina) and Japan, with a lighter, more melodic sound and frequent use of keyboards.
