Luxembourgers ( LUK-səm-bur-gərz; Luxembourgish: Lëtzebuerger [ˈlətsəbuəjɐ]) are a Germanic ethnic group native to their nation state of Luxembourg, where they make up around half of the population. They share the culture of Luxembourg and speak Luxembourgish, a West Germanic language.

Luxembourgers were, much like Austrians, historically considered to be a regional sub-group of ethnic Germans and viewed themselves as such until the collapse of the German Confederation. Luxembourg became independent, while remaining in personal union with the Netherlands, after the signing of the Treaty of London in 1839. The personal union proved short-lived as it was bilaterally and amicably dissolved in 1890.

Legally, all citizens of the Grand Duchy of Luxembourg are considered to be Luxembourgers per Luxembourgish law, although a distinct Germanic ethnolinguistic identification is vocally espoused and promoted. The corresponding adjective is "Luxembourgish".
