Trojane (pronounced [tɾɔˈjaːnɛ]; Latin: Atrans, German: Trojana[2]) is a settlement in the Municipality of Lukovica in central Slovenia.

The Romans built a road on the route connecting Aquileia, Emona, Atrans, and Celeia.

Trojane was an important way station, military post, and marketplace, and the town was surrounded by a defensive wall.

In the Roman Empire, Trojane (Atrans) was on the border between Italy and the province of Noricum.

Trojane is particularly known for the local restaurant's jelly doughnuts (Slovene: krofi), originally made with apricot jam filling.
