Ilamcetcenni (Tamil: இளம்சேட்சென்னி) was an early Tamil king of the Chola dynasty during the Sangam period. He was a great warrior and ruled the Chola kingdom with Puhar as the capital. He married a Velir Princess and the child born to the Royal couple was called Karikala Cholan. We don't have much details about his personal life. He was then succeeded by Karikala Chola, who is considered the greatest among the Early Cholas. He is considered to have good knowledge on making of 'Horse Cars'.
N.K. Sastri claims that this is the period where Magadha dynasty had established its empire from Persia to southern India. Bindusara son of Chandra Gupta Maurya conquered almost the whole India except Kalinga and Cholas. It is also mentioned that Ilanchetcheni had a good relation with Bindusara. But fragmentary poems of Sangam in the Purananuru states that, Ilamcetcenni successfully resisted the exploration of Mauryas down the southern region of the Indian subcontinent. Also Sastri claims that his period of reign is 301 BCE - 270 BCE and Cholas overpowered Cheras and Pandiyas at this time.
