Chanda Sahib (died 1752) is the Nawab of the Carnatic between 1749 and 1752.

His birth name is Husayn Dost Khan.

He is the son-in-law of the Nawab of Carnatic Dost Ali Khan, under whom he works as a Dewan.

He belongs to the Muslim Nait community which had ruled the Carnatic under the Nawab Zulfiqar Ali Khan during the reign of the Mughal Emperor Aurangzeb.

Chanda Sahib is an ally of the French and annexes the Madurai Nayak.

Declared the Nawab of Tanjore, he is weakened by constant Maratha attacks and is defeated by Muhammed Ali Khan Wallajah, who is allied to Nasir Jung.

After fleeing for safety, he attempts to recoup his losses but is beheaded in a mutiny by Hindu subjects in the Tanjore army.
