后物质主义(英语：Post-materialism)是指一个后现代的新理论：指一个由个体及社会所带动的一个持续的转变，使他们从基本的物质需要中释放出来的持续革命。 「后物质主义」这个概念及相关连的「宁静革命」是由政治及社会科学家朗奴·英高赫(Ronald Inglehart)于1970年代在他的著作《宁静革命—后物质主义价值变迁》(The Silent Revolution: Changing Values and Political Styles Among Western Publics)里所提出。

In sociology, post-materialism is the transformation of individual values from materialist, physical and economic to new individual values of autonomy and self-expression.

Post-materialism is a tool in developing an understanding of modern culture. It can be considered in reference of three distinct concepts of materialism. The first kind of materialism, and the one in reference to which the word post-materialism is used most often, refers to materialism as a value-system relating to the desire for fulfillment of material needs (such as security, sustenance and shelter) and an emphasis on material luxuries in a consumerist society. A second referent is the materialist conception of history held by many socialists, most notably Marx and Engels, as well as their philosophic concept of dialectical materialism. The third definition of materialism concerns the philosophical argument that matter is the only existing reality. The first concept is sociological, the second is both philosophical and sociological, and the third is philosophical.
