History & Origin

The origin of Arlo is genuinely uncertain. One theory links it to an Old English place-name element meaning 'fortified hill' or 'army hill.' Another suggests a connection to Spanish arlo, the common barberry shrub. Edmund Spenser referenced 'Arlo Hill' in The Faerie Queene, giving the name early literary cachet. It may also be an anglicization of Gaelic names.

Arlo gained significant cultural traction through folk musician Arlo Guthrie (b. 1947), son of Woody Guthrie and famous for the 18-minute talking blues song 'Alice's Restaurant Massacree' (1967). In the 21st century, the Pixar film The Good Dinosaur (2015) featured an Arlo protagonist. The name surged into the U.S. top 200 boys' names during the 2010s.

Did you know? Edmund Spenser used the toponym Arlo Hill in his epic poem The Faerie Queene (1596) — thought to be a reference to a real Irish hillfort — making Arlo one of the rare names with a Renaissance literary pedigree.
