Sthanu Ravi Varma, known as the Kulasekhara, was the Chera Perumal ruler of Kerala in southern India from 844/45 to 870/71 AD. He is the earliest Chera Perumal ruler known to scholars.

Cheraman Perumal dynasty, also known as the Perumal dynasty of Kerala, or Chera Perumals of Makotai, were a ruling dynasty in present-day Kerala, South India. Mahodayapuram, or Makotai, the seat of the Cheraman Perumals, is identified with present-day Kodungallur in central Kerala. Initially, their influence appeared limited to the area between present-day Quilon and Quilandy, but later extended to up to Chandragiri river in north Kerala and to Nagercoil in the south.
