TheGreen Party of Alaska^[50] is a political party in the U.S. state ofAlaska. It was the Alaska affiliate of the national stateGreen Party, from its creation until 2021, but the state party broke the party rules when it refused to recognize the nominated presidential candidate,Howie Hawkins in the2020 presidential election.^[51][52] Alaska was the first state to gain Green Partyballot access, in 1990, whenJim Sykes ran for governor. Sykes had previously filed a ballot access lawsuit, citing an earlier case,Vogler v.Miller.

Like theAlaska Libertarian Party, the Green Party organizes local affiliate groups by regions of the state rather than election districts. It is known for calling these groupsbioregions. The organized bioregions of the GPAK include the Southcentral Bioregion (Anchorage area) and the Tanana-Yukon Bioregion (the Interior, around the Tanana andYukon River areas).

TheGeorgia Green Party^[53] is a state-level political party in Georgia. Their candidate for president in 2016 was Dr.Jill Stein.^[54] Stein was denied access to the ballot.

TheOcean State Green Party (OSGP) is aGreen party in theUnited States. The party was founded in summer 2020, originally as a small group of supporters of theHawkins-Walker 2020 campaign inRhode Island. After the olderGreen Party of Rhode Island refused to support the presidential campaign,^[56] these supporters opted to reject this decision and collect signatures to gain a ballot line for the Green Party ticket. They then proceeded to file a complaint with the Accreditation Committee of the Green Party of the United States.^[57]

TheGreen Party of Rhode Island (GPRI) is one of the oldest activeGreen parties in the United States. The party was founded on March 6, 1992, at a meeting of 40 activists fromRhode Island. In November 1996, GPRI was one of 12 founding parties in theAssociation of State Green Parties, renamed the Green Party of the United States in 2001. Several Rhode Island party leaders have served as officers of the national Green Party. The party's candidates run for municipal councils in several cities and towns, such as running for Mayor ofProvidence,the State Senate andthe State House of Representatives,U.S. Congress, and forLieutenant governor. The Green Party of Rhode Island was involved in nationwideGreen politics, until 2020 when the state party leadership took the rogue position to refuse to place the Green nominee for President,Howie Hawkins, on the ballot. Rather than face deaccreditation, the state party ended its affiliation with GPUS.

TheIndependent Greens of Virginia, (also known as theIndy Greens), was the state affiliate of theIndependence Party of America in the Commonwealth ofVirginia. It became a state party around 2003 when a faction of theArlington local chapter of theGreen Party of Virginia (GPVA) split from the main party. As of 2011, it bills itself as a "fiscally conservative, socially responsible green party", with an emphasis on rail transportation and "more candidates".^[58] In support of wider ballot participation, it endorses many independent candidates who are not affiliated with the party.
