Austrians () are the citizens and nationals of Austria. The English term "Austrians" was used for the population of Habsburg Austria from the 17th or 18th century. During the 19th century, it was for the citizens of the Empire of Austria (1804–1867). From 1867 until 1918, it was used for the citizens of Cisleithania. The term "Austria" first referred to the historical March of Austria. This was mostly the Vienna Basin in what is today Lower Austria.
