Sir Charles Bunbury, 4th Baronet (9 February 1708 – 10 April 1742) was a British politician.
The member of an ancient Cheshire family, Bunbury was the eldest son of Sir Henry Bunbury, 3rd Baronet, and his wife Susannah, daughter of William Hanmer. Sir Charles Bunbury and Henry Bunbury were his nephews. He was returned to Parliament as one of two representatives for Chester in 1733, a seat he held until his death.
Bunbury died after a long illness in April 1742, aged 34. He never married and was succeeded in the baronetcy by his younger brother, William.
