The seat of the municipality is the city of Nova Gorica. Nova Gorica became a municipality in 1994. It borders Italy.

In addition to the municipal seat of Nova Gorica, the municipality also includes the following settlements:

The municipality of Nova Gorica is governed by a mayor, elected every four years by popular vote, and a city council of 32 members. Both in local and national elections, Nova Gorica has been considered an electoral stronghold of the left, in particular of the Social Democrats. Between the early 1990s and the mid-2000s, the two major political parties in the town were the Social Democrats and Liberal Democracy of Slovenia, both considered center-left parties. Since 1994, these two parties have been alternating in power at the local level, running candidates against each other and forming coalitions with smaller center-right parties in order to gain an absolute majority in the city council.

The Nova Gorica electoral district is the home district of Borut Pahor, former prime minister and current president of Slovenia; it was also the only district in the country where the Social Democrats won the plurality of votes in the 2011 elections.
