The following is a list of political organizations in the United States which support left-wing politics: social democracy, socialism, communism, or anarchism.
The list below focuses on creation, splits, merges, and ends of various leftist organizations. This page hopes to outline the extremely messy organizational history of leftism and socialism in the United States. This page also hopes to help readers see that the US history of leftism and history of socialism has deep roots that stretch back to 1848 and earlier.
This page focuses on mass organizations: Leftist orgs which have a mass dues-paying membership, which claimed to have one, or which planned to build one. Many are organized as political parties. Many reject electoral politics altogether. This criterion excludes most organizations focused on publishing media, small collectives with no focus on growth, terrorism, and clandestine cells. Some major paramilitary organizations are included, if they hoped to use propaganda of the deed to achieve socialist revolution or emerged from mass organizations (such as the Weathermen).
This page focus on overtly leftist organizations: Organizations which are capitalism-critical or anti-capitalist. Some progressive capitalist organizations are included, because they have a substantial leftist membership or were critical to the formation of a leftist group. Some major labor federations are included, despite few labor federations explicitly adopting anti-capitalist rhetoric, because labor federation competition is often intertwined with competition between leftist organizations.
The "eras" below describe major movements of socialists or which substantially affected the nature of socialist organizing in the United States.

These groups are not notable and are also not clearly tied to any notable groups:
The organizations below have sometimes been, incorrectly, described as having socialist politics:
TODO: """ACORN in the West, Massachusetts Fair Share in the East, the Highlander Center in Appalachia, TWO in Chicago, SEASHA and the Federation of Southern Cooperatives in the South are some of the many ongoing democratic experiments that deserve support and encouragement. [....] The lesson of recent history is that such programs need to be shaped and instituted by citizens themselves. This requires marshalling of power at the ballot box and within the only political party at all receptive to the needs of the disenfranchised, the Democratic party.""" https://democracyjournalarchive.files.wordpress.com/2015/06/berman_mainstream-politics-democracy-3-2_-may-1983.pdf
