Antonio Arrúe Zarauz (1903–1976) was a Spanish politician and a Basque cultural activist.
Politically he was a Carlist militant throughout all of his life; in the 1950s and 1960s Arrue informally led the Gipuzkoan branch of the party, and in 1957-1959 he held the official Traditionalist jefatura in the province.
His political climax fell on 1967-1971, when he served in the Cortes elected from the so-called tercio familiar.
He contributed to Basque culture mostly as organizer and administrator, during the Francoist era engaged especially in Euskaltzaindia.
His input as linguist or ethnographer is moderate, though he excelled as one of the best Basque-language orators of his time.
