Marbury v. Madison is significant because it established the principle of judicial review in the United States. This landmark case, decided in 1803, allowed the Supreme Court to declare an act of Congress unconstitutional, thus affirming the judiciary's role in interpreting the Constitution and checking the powers of the other branches of government.

By establishing judicial review, the Supreme Court gained the authority to evaluate the legality and constitutionality of legislative and executive actions. This principle has since become a cornerstone of American constitutional law, enabling the judicial branch to play a vital role in the system of checks and balances that underpins the government.

While the separation of powers, federal supremacy, and states' rights are also important concepts in U.S. law, they are not the primary significance of Marbury v. Madison. The case specifically centers on the judiciary's authority to review the constitutionality of governmental actions.
