万尼瓦尔·布什（Vannevar Bush，1890年3月11日－1974年6月30日），美国著名工程师，科学家管理者。

他于二战期间为曼哈顿计划发挥了巨大的政治作用。后来布希写了“Science, the Endless Frontier”科学,无尽的边疆一文给小罗斯福总统，建议美国政府大力支持科学研究，而且政府不需自己设立研究机构，只需提供研究经费，让大学和私人企业依照研究表现来竞争政府的研究经费。此后美国政府提供的科学研究经费大幅增加，研究成果也很杰出成为全球科技第一的国家。在他的一篇文章中As We May Think提出memex这一概念，可以被看成为是现代万维网的先锋。

Vannevar Bush (/væˈniːvɑːr/ van-NEE-var; March 11, 1890 – June 28, 1974) was an American engineer, inventor and science administrator, who during World War II headed the U.S. Office of Scientific Research and Development (OSRD), through which almost all wartime military R&D was carried out, including initiation and early administration of the Manhattan Project. He is also known in engineering for his work on analog computers, for founding Raytheon, and for the memex, a hypothetical adjustable microfilm viewer with a structure analogous to that of hypertext. In 1945, Bush published the essay "As We May Think" in which he predicted that "wholly new forms of encyclopedias will appear, ready made with a mesh of associative trails running through them, ready to be dropped into the memex and there amplified". The memex influenced generations of computer scientists, who drew inspiration from its vision of the future. He was chiefly responsible for the movement that led to the creation of the National Science Foundation.
