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 member of the Irumporai/Porai line, a collateral branch of the Chera family, which had its headquarters at Karuvur (Karur) in the interior Tamil country. He is also described as the ruler of Thondi (on the Malabar Coast), the "land the mountain fence protects", and the king of Kuda Nadu.

Mantharan Cheral 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.
