长石（英语：feldspar）是长石族矿物的总称，是地壳中最重要的造岩成分，比例达到60%。
长石的主要化学成分包括钾、钠、钙、钡等元素的铝硅酸盐矿物（KAlSi3O8 - NaAlSi3O8 - CaAl2Si2O8）。
长石是在侵入火成岩或喷出火成岩中的岩浆的结晶体，形成矿脉；也可存在于多种变质岩中。几乎完全由钙质斜长石形成的岩石称作斜长岩。在多种沉积岩中也发现了长石。另外月球的壳也由长石组成。

Feldspars (KAlSi3O8 – NaAlSi3O8 – CaAl2Si2O8) are a group of rock-forming tectosilicate minerals that make up as much as 60% of the Earth's crust.
Feldspars crystallize from magma as veins in both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar (see below) is known as anorthosite. Feldspars are also found in many types of sedimentary rocks.
