Rožna Dolina (pronounced [ˈɾoːʒna dɔˈliːna]; Italian: Valdirose, German: Rosenthal) is one of the four suburbs of the town of Nova Gorica in western Slovenia (the others being Solkan, Kromberk, and Pristava).

Before 1947, it used to be a suburb of the town of Gorizia, which was left to Italy in the Paris Peace Conference of February 1947.

[2] It was the site of one of the major engagements in the Ten-Day War for the independence of Slovenia in June 1991.

Lucy Christalnigg, first victim on the Isonzo Front, was a resident of Rožna Dolina.

She was on her way back to Rožna Dolina in August 1914, when she was shot by two Landsturm guards at a roadblock.
