Alejandro María Daniel Irujo Urra (1862-1911) was a Spanish lawyer. In popular discourse he is known as father of Manuel Irujo Ollo, a Basque political leader. In scholarly historiographic realm he is acknowledged mostly as defense attorney of Sabino Arana during his trials of 1896 and 1902. Politically Irujo is considered a typical case of an identity located in-between Carlism and emerging Spain's peripheral nationalisms, in this case the Basque one.
