Basiliscus (; ) (d. 476/477) was Eastern Roman (Byzantine) Emperor from 475 to 476. A member of the House of Leo, he came to power when Emperor Zeno had been forced out of Constantinople by a revolt. Basiliscus was the brother of Empress Aelia Verina, the wife of Emperor Leo I (457–474). His relationship with the Emperor allowed him to pursue a military career that, after minor initial successes, ended in 468, when he led the disastrous Roman invasion of Vandal Africa, in one of the largest military operations of Late Antiquity.
