In Greek mythology, Agelasta (Ancient Greek: Ἀγέλαστος, Greek: Αγέλαστη, "smile-less") was the name of the stone on which Demeter rested during her search for Persephone.

In modern culture, Agelasta inspired the title of a documentary by Philippos Koutsaftis (Φίλιππος Κουτσαφτής), called Agelastos Petra (Αγέλαστος Πέτρα, "smile-less stone", 2000).
