Bandi Sailu (1928 – 15 July 2000) or Sayilu Saayilu was a Marxist revolutionary born in a Dalit family in Mandapelli village, Duggondi mandal, Narsampeta Thalukh in the Warangal district of Andhra Pradesh, India.
In Warangal District, particularly Narsampeta and Mahboobabad Thalukh, he attacked many feudalist gadhis with his group.
He organized many attacks against the Nizam and Rajakars, and seized lands and distributed thousands of acres to landless poor people.
He left politics when Omkar was defeated by Revuri Prakash Reddy (Telugu Desam Party) in the 1994 election by only 25 votes.
Bandi Sailu felt that Prakash Reddy won the election by spending money and in illegal ways.
