Albite is a plagioclase feldspar mineral. It is the sodium endmember of the plagioclase solid solution series. It represents a plagioclase with less than 10% anorthite content. The pure albite endmember has the formula . It is a tectosilicate. Its color is usually pure white, hence its name from Latin, . It is a common constituent in felsic rocks.

钠长石（英語：Albite）是钠的（NaAlSi3O8），为三斜晶系的玻璃状晶体，一般为无色、白色、黄色、红色或黑色，是长石的一类。钠长石为架状硅酸盐结构，比重2.62，莫氏硬度为6 - 6.5，其中钙长石的含量少于10%。 钠长石是斜长石固溶体系列的钠质矿物，在伟晶岩和花岗岩中最为常见，1815年首先於瑞典发现。
