Antlia (/ˈæntliə/; from Ancient Greek ἀντλία) is a constellation in the southern sky. Its name means "pump" and it specifically represents an air pump. Abbreviated from Antlia Pneumatica, the constellation was introduced by Nicolas Louis de Lacaille in the 18th century. Located close to those forming the old constellation of the ship Argo Navis, Antlia is completely visible from latitudes south of 49 degrees north.
