The term Federalists refers, in the context of the founding era of the United States, to a political faction and later political party that supported ratification of the United States Constitution of 1787 and, in the 1790s, coalesced around the policies of Alexander Hamilton and the administrations of George Washington and John Adams. The term carries two related but distinct senses: (1) the broader coalition of delegates, writers, and citizens who advocated for ratifying the Constitution during the 1787-1788 ratification debates, and (2) the more specific Federalist Party that formed afterward as one of the first two organized political parties in the United States, opposed by the Democratic-Republicans. Some scholars distinguish these two uses more sharply than others; see federalists-terminology-viewpoint.

The Federalists are most closely associated with The Federalist Papers, a series of 85 essays written by Alexander Hamilton, James Madison, and John Jay under the pseudonym “Publius,” published between 1787 and 1788 to advocate for ratification of the Constitution. Their principal opponents in the ratification debate are known as the Anti-Federalists; the relative characterization of each side's conduct during that debate is itself disputed, see federalists-anti-federalists-viewpoint-debate.

Historians broadly agree on the basic chronology and identity of leading Federalist figures, including Hamilton, Madison (in his pre-1791 capacity, before he later aligned with the Democratic-Republicans), Jay, Washington, Adams, and others such as Rufus King, Fisher Ames, and John Marshall. There is also general agreement that the Federalist Party, as a distinct political organization, declined sharply after 1800 and effectively dissolved as a national force following the War of 1812 and the Hartford Convention of 1814-1815, with the “Era of Good Feelings” that followed marked by the temporary absence of organized party competition.

Disagreement persists, however, on several interpretive questions: the degree to which Federalist support for a strong central government reflected genuine constitutional philosophy versus the economic interests of creditors, merchants, and large property holders; the extent to which the Federalist Party's later association with policies favoring centralized authority (e.g., the Alien and Sedition Acts of 1798) represents a continuous thread from the ratification-era Federalists or a distinct later development; and how to characterize the Federalists' views on executive power, judicial review, and the proper scope of federal authority relative to the states. These interpretive disputes are treated in federalists-continuity-debate and federalists-motives-debate.

A fuller historical account, including the ratification campaign, the formation of Washington's administration, the Hamilton-Jefferson rivalry, the Alien and Sedition Acts, and the party's decline, is available at federalists-history.

• Constitutionalist viewpoint: Federalists are best understood as constitutional theorists who believed a stronger national government was necessary to remedy the demonstrated weaknesses of the Articles of Confederation, particularly regarding interstate commerce, national defense, and the inability to enforce treaties or collect revenue. See federalists-constitutionalist-viewpoint.
• Economic-interest viewpoint: Federalist support for the Constitution and for Hamiltonian financial policy is best explained primarily by the economic interests of bondholders, merchants, and propertied elites who stood to benefit from a stronger national government capable of assuming state debts and stabilizing currency and credit. See federalists-economic-interest-viewpoint.
• Critical/civil-liberties viewpoint: Federalist governance, particularly under Adams, is best characterized by its willingness to suppress dissent and restrict civil liberties, as exemplified by the Alien and Sedition Acts, reflecting an elitist distrust of popular democracy. See federalists-civil-liberties-critical-viewpoint.
• Institutional-continuity viewpoint: The Federalists' core constitutional commitments - judicial review, implied powers, a national bank, and a strong executive - established institutional precedents that persisted in American governance well beyond the party's dissolution, independent of the party's own electoral fate. See federalists-institutional-continuity-viewpoint.
• Elitist/anti-democratic viewpoint: Some Federalists, including Hamilton, expressed skepticism of direct popular rule and favored a government structure with greater insulation from popular passions, a stance critics characterize as fundamentally anti-democratic. See federalists-elitist-viewpoint.

• The Alien and Sedition Acts of 1798, enacted under the Adams administration, prompted sustained dispute over their constitutionality and their use against political opponents, and remain a focal point in assessments of the Federalist Party's record on civil liberties. See federalists-alien-sedition-acts-controversy.
• The Hartford Convention of 1814-1815, in which New England Federalists discussed grievances against the war policies of the Madison administration and potential constitutional amendments, was widely denounced by opponents as bordering on secessionist, a charge that contributed to the party's national decline. See federalists-hartford-convention-controversy.
