肯塔基及弗吉尼亚决议案是弗吉尼亚州和肯塔基州议会为抗议联邦政府的《客籍法和镇压叛乱法》而通过的议案。《弗吉尼亚决议案》由麦迪逊起草，1798年12月24日州议会通过。《肯塔基决议案》由副总统杰弗逊起草，布雷肯里奇（John Breckenridge）提出,1798年11月16日州议会通过。

The Kentucky and Virginia Resolutions (or Resolves) were political statements drafted in 1798 and 1799, in which the Kentucky and Virginia legislatures took the position that the federal Alien and Sedition Acts were unconstitutional. The resolutions argued that the states had the right and the duty to declare unconstitutional acts of Congress that were not authorized by the Constitution. In doing so, they argued for states' rights and strict constructionism of the Constitution. The Kentucky and Virginia Resolutions of 1798 were written secretly by Vice President Thomas Jefferson and James Madison, respectively.
