SI:Rupnikova linija je bila obsežen sistem utrdb, ki so jih v 30. letih 20. stoletja gradili v Kraljevini Jugoslaviji, predvsem na slovenskem ozemlju. Linija je dobila ime po generalu Leonu Rupniku, ki je vodil gradnjo. Namenjena je bila obrambi pred morebitnim napadom Italije. Kljub obsežnim gradnim delom utrdbe niso nikoli bile uporabljene v vojni, saj je Jugoslavija bila napadena že pred dokončanjem. Danes so ostanki Rupnikove linije pomembna kulturna in zgodovinska dediščina.
EN: Rupnik's line was an extensive system of fortifications built in the 1930s in the Kingdom of Yugoslavia, mainly on Slovenian territory. The line was named after General Leon Rupnik, who led the construction. It was intended to defend against a possible attack by Italy. Despite extensive construction work, the forts were never used in war, as Yugoslavia was invaded before completion. Today, the remains of Rupnik's line are an important cultural and historical heritage.
