Tukkoji Bhonsle (1677–1736) was the fourth Maratha ruler of Thanjavur, located in South India.

He was from the Bhonsle dynasty and was the son of Ekoji I as well as the younger brother of Shahuji I and Serfoji I. Tukkoji ruled Thanjavur from 1728 to 1736.

Tukkoji succeeded his brother Serfoji I to the throne of Thanjavur on the former's death in 1728 and is believed to have reigned until 1736.

Unlike his brother, however, he switched over to Bhavani Shankar's side and helped the latter attain the throne.

Marathi inscriptions of this period record Tukkoji's aid to Meenakshi the Queen of Tiruchirapalli against the Palaiyakkarar who rose in revolt against her.
