美国国家航空暨太空法案(National Aeronautics and Space Act)是创制出美国国家航空暨太空总署（NASA）的美国联邦法案。在苏联发射人造卫星后，美国众议院航空暨太空探索委员会就紧跟着草拟了法案，并于1958年7月29日由美国总统艾森豪签署通过。在这法案之前，因为苏联发射第一颗卫星的模式，太空探索被视为一种军事行为。这法案的制定很大程度上是因为军事设施似乎已经无法跟上太空竞赛了。

除了创建NASA，还将先前创建的国家航空咨询委员会(NACA)转型成一个可以直接向总统报告的独立机构。这法案也创建了民间军事咨询委员会(Civilian-Military Advisory Panel)，在加州的范登堡空军基地负责提供咨询级协调太空的军事用途。因为先前许多发射军事和监探设施的介入和为预先计划反制苏联的核武器进入太空所制定的部分禁止核试验条约，现在美国已经将军事和民间太空计划分开了。

The National Aeronautics and Space Act of 1958 (Pub.L. 85–568) is the United States federal statute that created the National Aeronautics and Space Administration (NASA). The Act, which followed close on the heels of the Soviet Union's launch of Sputnik, was drafted by the United States House Select Committee on Astronautics and Space Exploration and on July 29, 1958 was signed by President Eisenhower. Prior to enactment, the responsibility for space exploration was deemed primarily a military venture, in line with the Soviet model that had launched the first orbital satellite. In large measure, the Act was prompted by the lack of response by a US military infrastructure that seemed incapable of keeping up the space race.
