In ancient Roman religion, an aedicula (plural aediculae) is a small shrine. The word aedicula is the diminutive of the Latin aedes, a temple building or house.

Many aediculae were household shrines that held small altars or statues of the Lares and Penates. The Lares were Roman deities protecting the house and the family household gods. The Penates were originally patron gods (really genii) of the storeroom, later becoming household gods guarding the entire house.
