In ancient Roman religion, Ops or Opis (Latin: "Plenty") was a fertility deity and earth goddess of Sabine origin.

In Ops's statues and coins, she is figured sitting down, as Chthonian deities normally are, and generally holds a scepter, or a corn spray and cornucopia.

In Latin writings of the time, the singular nominative (Ops) is not attested; only the form Opis is used by classical authors.

[3] This activity was deemed sacred, and was often attended by religious rites intended to obtain the good will of chthonic deities such as Ops and Consus.

She is remembered in De Mulieribus Claris, a collection of biographies of historical and mythological women by the Florentine author Giovanni Boccaccio, composed in 1361–1362.
