Aergia (Greek: Ἀεργία, "inactivity") is a goddess in Greek mythology, a personification of sloth and laziness. She is the daughter of Aether and Gaia. She is said to guard the court of Hypnos in the Underworld.
Aergia is the transliteration of the Latin Socordia, or Ignavia. She was transliterated to Greek because Hyginus mentioned her based on a Greek source, and thus can be considered as both a Greek and Roman goddess. Her opposite character is Horme, a goddess of effort.
