Nova Gorica is a town in western Slovenia, on the border with Italy. It is the seat of the Municipality of Nova Gorica. Nova Gorica is a planned town, built according to the principles of modernist architecture after 1947, when the Paris Peace Treaty established a new border between Yugoslavia and Italy, leaving nearby Gorizia outside the borders of Yugoslavia and thus cutting off the Soca Valley, the Vipava Valley, the Gorizia Hills and the northwestern Karst Plateau from their traditional regional urban centre. Since 1948, Nova Gorica has replaced Gorizia as the principal urban centre of the Gorizia region, as the northern part of the Slovenian Littoral has been traditionally called.

Since May 2011, Nova Gorica has been joined together with Gorizia and Šempeter-Vrtojba in a common trans-border metropolitan zone, administered by a joint administration board.

To the south of the town stands Kostanjevica Hill, home to the Church of the Annunciation of Our Lady and a 17th-century Franciscan monastery with rich treasures from the past. The last members of the Bourbons, the French royal family, are buried in a crypt beneath the church (Charles X himself, and members of his family and entourage including his son Louis-Antoine de France, and his grandson Henri d'Artois, nephew of Louis (neither Louis-Antoine nor Henri ever reigned as kings)). He fled France following the revolution in 1830, finding refuge in Gorizia, and eventually died there. Also buried there is Pierre Louis Jean Casimir de Blacas, a Bourbon nobleman who also died in exile (in 1839).
