This list of political parties in the United States identifies notable political parties in the United States, both past and present, both major and minor. Notes:
- The list does not include independents, whose notable election runs can be found at list of independent performances in United States elections.
- Voter registration numbers below should be taken as a lower bound, because not all states allow public access to voter registration data.
- Abbreviations come from the parties themselves and from state ballots used in the most recent elections. Not all parties have abbreviations.
- Ballot access comes from a variety of sources including Ballotpedia, The Green Papers, and various state Secretaries of State.
- The "political positions" and "ideology" for each party merely repeat the main article on that political party. For example, if the Democratic Party (United States) page states "center to center-left" and "liberalism", this page will repeat that.
- For political parties in Puerto Rico, an unincorporated territory of the US, see List of political parties in Puerto Rico.

Party registration
Officially recognized parties in states are not guaranteed to have ballot access, membership numbers of some parties with ballot access are not tracked, and vice versa. Not all of these parties are active, and not all states record voter registration by party. Boxes in gray mean that the specific party's registration is not reported.
