信息化革命，或信息革命，是指信息技术（亦即IT）的发展，以互联网于全球化普及为重要标志。

从1980年代个人电脑普及开始，信息的传递变得越来越简便、快捷、廉价，人们寻求一种更快捷的通信方式，恰恰美国将用于军事、商业的网络完全开放，形成实际意义的互联网。网络的发展令网络软件应运而生，即时通讯软件、电邮令分隔两地的人可以于短时间内实现通讯。它完全打破了地域、距离、意识形态的限制，使人们能接触到各种思想、文化，更主要的是实现了信息的即时性。前期的互联网称为Web 1.0，是指其只实现了单向的信息广播，而目前正处于Web 2.0的过渡之中，即通过互联网实现各种互动。

The term information revolution describes current economic, social and technological trends beyond the Industrial Revolution.

Many competing terms have been proposed that focus on different aspects of this societal development. The British polymath crystallographer J. D. Bernal introduced the term "scientific and technical revolution" in his 1939 book The Social Function of Science to describe the new role that science and technology are coming to play within society. He asserted that science is becoming a "productive force", using the Marxist Theory of Productive Forces. After some controversy, the term was taken up by authors and institutions of the then-Soviet Bloc. Their aim was to show that socialism was a safe home for the scientific and technical ("technological" for some authors) revolution, referred to by the acronym STR. The book Civilization at the Crossroads, edited by the Czech philosopher Radovan Richta (1969), became a standard reference for this topic.
