油价，也称原油价格，是一种石油现货交易时所使用的价值度量，是一桶标准原油的价格。

最主要的标准原油油价有：西得克萨斯中间基原油（WTI）、北海布兰特原油及杜拜原油。

原油价格和其等级高度相关，等级会依照其比重（或API比重）、其含硫量及其出产地点有关。其他常见的原油价格有马来西亚的塔皮斯原油（Tapis）、OPEC原油价格、阿格斯含硫原油价格指数（ASCI）等。美国能源情报署（EIA）整理进口精炼原油的价格，加权平均后得到「世界原油价格」。

原油需求和世界整体经济条件有高度的相关性，根据国际能源署的数据，高油价会对全球经济成长有相关负面的影响。

The price of oil, or the oil price, generally refers to the spot price of a barrel of benchmark crude oil—a reference price for buyers and sellers of crude oil such as West Texas Intermediate (WTI), Brent ICE, Dubai Crude, OPEC Reference Basket, Tapis Crude, Bonny Light, Urals oil, Isthmus and Western Canadian Select (WCS). There is a differential in the price of a barrel of oil based on its grade—determined by factors such as its specific gravity or API and its sulphur content—and its location—for example, its proximity to tidewater and/or refineries. Heavier, sour crude oils lacking in tidewater access—such as Western Canadian Select— are less expensive than lighter, sweeter oil—such as WTI.
