The Aldara was a Cardassian Galor-class cruiser that was in service with the Cardassian military in the mid-24th century. In the late 2360s, the Aldara was under the command of Gul Danar.
In 2369, the Aldara pursued a Bajoran scout ship carrying Bajoran terrorist Tahna Los into the Bajoran system after he stole an antimatter converter from a Cardassian outpost. Commander Benjamin Sisko later contacted the Aldara to seek Gul Danar's help in stopping Tahna destroying the Bajoran wormhole, although the Aldara was too distant to assist. (DS9: "Past Prologue")
