Rauchya Manvantara is the ninth manvantara. It is named after Ruchi–Manu and will be called Rauchya manvantara. Ruchi Manu will have a son named Rauchya.
Each manvantara is ruled over by a Manu. In the present kalpa, six manvantaras have already passed and the names of the six Manus who ruled were Svayambhuva, Svarochisha, Uttama, Tamasa, Raivata and Chakshusha.

The titles of the seven great sages (saptarshi) as well as the tile of Indra change from manvantara to manvantara. The gods also change.
