The Baths of Commodus (Latin: "Thermae Comodianae") or Baths of Cleander (Latin: "Thermae Cleandri") was a thermae (baths) complex in Rome, in Regio I Porta Capena, presumably to the south or south-east of the Baths of Caracalla. Although mentioned by several ancient authors no archaeological remains survive.
They were built by Marcus Aurelius Cleander, a favourite of the emperor Commodus and dedicated in 183, in the fourth year of Commodus' reign.
It included a gymnasium.
