Arlo is an English given name of uncertain origin. It was perhaps inspired by the fictional place name Arlo Hill from the 1590 poem The Faerie Queene by Edmund Spenser. In the poem, Arlo Hill is the setting where the gods debate. Spenser is thought to have derived the name by altering the Irish place name Aherlow, meaning "between two highlands." Alternatively, some sources suggest an Old English origin, with the meaning "endless energy."
