De Bello Alexandrino (also Bellum Alexandrinum; On the Alexandrine War) is a Latin work continuing Julius Caesar's commentaries, De Bello Gallico and De Bello Civili. It details Caesar's campaigns in Alexandria and Asia. Though normally collected and bound with Caesar's authentic writings, the authorship of the work has been debated since antiquity. Suetonius suggests both Oppius and Hirtius as possible authors.
