Arlo is a stylish English name with an uncertain exact meaning. Behind the Name gives its strongest route as a literary and place-name-inspired form rather than a neat inherited definition.
The name may have been inspired by Arlo Hill in Spenser's The Faerie Queene, with that form likely influenced by the Irish place name Aherlow. Modern popularity has much more to do with sound and style than with a single simple literal meaning.
