Sir Charles John Wingfield KCSI CB (16 April 1820 – 27 January 1892) was a British civil servant and politician.

[3] William changed his surname to Wingfield-Baker in 1849 by Royal licensure after his inheritance of Orsett Hall in Essex.

From William's first marriage to Lady Charlotte-Maria (died 1807), eldest daughter of Henry Digby, 1st Earl Digby, Wingfield had several older half siblings including: George-Digby, John-Digby, Mary, Caroline, Frances-Eliza, and Richard Baker Wingfield-Baker, a member of parliament for South Essex.

[14] In his will (proved on 4 March 1892[14]), Wingfield bequeathed money to at least two charities, including the London and the National Dental Hospitals.

[15] The 80-acre (320,000 m2) Wingfield Park, named in his honour, is half a mile south of Sikandar Bagh in Lucknow, Uttar Pradesh, India.
