Lobon of Argos was an epigrammatist from Argos active in the 3rd century BCE. No details of his life beyond his origin and literary activity are recorded. His known works survive only in fragments and later references. These consist of a collection of poetic epigrams and a lost prose work entitled On Poets, both cited by authors such as Diogenes Laërtius.

Lobon holds a minor but notable place due to his reputation for forgery. Diogenes Laërtius reports that Lobon affixed spurious verses to the poets and composed fictitious verses attributed to philosophers. Consequently, while used by later compilers, his works are treated with skepticism, representing a clear example of Hellenistic pseudepigraphical activity.
