Mantharan Cheral Irumporai

Mantharan Cheral Irumporai (Tamil: மாந்தரன் சேரல் இரும்பொறை, title "Yanai Katchai", fl. c. 215 CE) was a ruler of the Chera dynasty in early historic south India (c. 1st - 4th century CE).

He was a contemporary of the Pandya ruler Nedum Chezhian (II, early 3rd century CE). His death was famously portended by a falling star (possibly a comet or meteor).

Mantharan Cheral was a member of the Irumporai/Porai line, a collateral branch of the Chera family (ruling with Karuvur/Karur as their headquarters). He is described as the ruler of Thondi (on the Malabar Coast), the "land the mountain fence protects", and the king of Kuda Nadu.
