Fabius Valens of Anagnia (d. 69) was a Roman commander favoured by Nero. In 69 he was commander of Legio I Germanica based in Germania Inferior. When the troops refused to endorse the new emperor Galba after Nero's death, he had them proclaim Vitellius, the governor of Germania Inferior, as emperor. One anecdote says that he appeared on the music-stage hall at Nero's coming of age celebrations, not at the command of Nero but voluntarily. At the time this was frowned upon, and many people thought that he was merely a man of fashion.
