The ovation (Latin: ovatio from ovare: to rejoice) was a form of the Roman triumph. Ovations were granted when war was not declared between enemies on the level of nations or states; when an enemy was considered basely inferior (e.g., slaves, pirates); or when the general conflict was resolved with little or no danger to the army itself. The Ovation could also be given rather than a triumph when there were extenuating circumstances, such as when Marcus Marcellus was given an ovation in lieu of a triumph as his army remained in Sicily and therefore was unable to cross the pomerium.

The general celebrating the ovation did not enter the city on a biga, a chariot pulled by two white horses, as generals celebrating triumphs did, but instead rode on horseback in the toga praetexta of a magistrate.

The honoured general also wore a wreath of myrtle (sacred to Venus) upon his brow, rather than the triumphal wreath of laurel. The Roman Senate did not precede the general, nor did soldiers usually participate in the procession.

Perhaps the most famous ovation in history is that which Marcus Licinius Crassus celebrated after his victory of the Third Servile War.
