Thuljaji Bhonsle (Marathi: तुळजाजी, also known as Tullasu Rasa) (1738–1787) was the eldest son of Pratap Singh and the ruler of Thanjavur Bhonsle dynasty from 1763 to 1773 and 1776 to 1787. He was a weak-hearted ruler despite being extremely generous. His period is known for the treaties which made Thanjavur subordinate to the British East India Company.
