Bertrange (French pronunciation: [bɛʁtʁɑ̃ʒ]; Luxembourgish: Bartreng [ˈbɑχtʀeŋ] ⓘ; German: Bartringen [baʁtʁɪŋən]) is a commune and town in south-western Luxembourg.

To the north of the town of Bertrange, on the other side of the route d'Arlon, is the village of Tossenberg, next to which is Luxembourg's largest shopping centre, La Belle Etoile.

The Treveri, a Gallic tribe, inhabited the region for several hundred years until they were conquered by Julius Caesar in 54 BC.

It passed through Strassen (Strata) to what is now Bertrange at Tossenberg where there was a refreshment post for travellers and continued to nearby Mamer (Mambra), a Roman vicus, and Arlon (Orolauneum).

[1] There was probably a feudal castle in Bertrange as its lords are mentioned in documents establishing the freedom of Echternach in 1226 and of Luxembourg in 1243.
