|Guianese Assembly (fr)|
It was founded in 1956 by Justin Catayée, beforehand the founder of the Guianese federation of the French Section of the Workers' International (SFIO). It is a separate party, not to be confused with the departmental federation of the French Socialist Party. For instance, the PSG endorsed the overseas list of Europe Ecology - The Greens, not the PS one, in the 2004 European elections.
The PSG candidate Gabriel Serville won one of the two parliamentary seats for French Guiana at the French National Assembly in 2012, the second one was held in 2007-2017 by a non-PSG deputy, Chantal Berthelot, endorsed by various parties, among whom the PSG.
The PSG was until 2010 a major party in the regional council of French Guiana, when it fell from 17 seats to one out of 31. It controls since then only the Cayenne municipality. The PSG didn't compete as such for the December 2015 first Guianese Assembly elections after the merger of the department and the region, and the coalition list it supported, headed by deputy Chantal Berthelot from another left-wing party, got only 8.49% and was eliminated at the first round.
Rodolphe Alexandre, then PSG first alderman in Cayenne, was excluded from the party in January 2008 for presenting a list against the incumbent PSG mayor. He won the 2008 municipal election and became mayor, then won the 2010 regional elections and became president of the Regional Council, likewise for the 2015 Guianese Assembly.
French Guiana sends two deputies in Paris since 1988, beforehand only one. The electoral districts borders were considerably modified before the 2012 elections.

For the first elections to the Guianese Assembly in December 2015, the PSG did not compete as such but on a common list Cultiver la Guyane led by the deputy Chantal Berthelot of the party To the Left in Guiana (AGEG)(fr). The list got 8.49% of the votes in the first round, under the 10% threshold needed to access to the second round. Only two lists could compete for the second round and both their leaders refused any merger with lists that had got between 5% and 10% for the first round, thus eliminating from the new assembly the PSG, but also all the other parties hitherto represented in one or both previous councils: AGEG, Walwari (Christiane Taubira's party), MDES and LR.
