Thaikkattusery Sankara Warrier (c. 1797 - 23 October 1856) was an Indian civil servant and administrator who served as the Diwan of the Kingdom of Cochin from 1840 to 1856.
Sankara Warrier was born in a poor Ambalavasi family in Ollur village near Trichur in January 1797.
After his early schooling in Sanskrit, Warrier migrated to Ernakulam at the age of 17 and took employment as a clerk in the Appeal Court.
As Diwan he was noted for his administrative abilities, which enabled Cochin to rise to the forefront among princely states.
Sankara Warrier is, especially, remembered for prevailing upon the Maharaja to issue a proclamation abolishing slavery on 16 February 1854.
