The [[Antlia Cluster]], also known as Abell S0636, is a [[galaxy cluster|cluster of galaxies]] located in the [[Hydra–Centaurus Supercluster]]. It is the third nearest to the [[Local Group]] after the [[Virgo Cluster]] and the [[Fornax Cluster]].<ref name="SmithCastelli2008">{{Cite journal | last1 = Smith Castelli | first1 = Analía V. | last2 = Bassino | first2 = Lilia P. | last3 = Richtler | first3 = Tom | last4 = Cellone | first4 = Sergio A. | last5 = Aruta | first5 = Cristian | last6 = Infante | first6 = Leopoldo | title = Galaxy populations in the Antlia cluster – I.
