Sir Charles Wentworth Dilke, 1st Baronet (18 February 1810 – 10 May 1869), was an English art patron, horticulturalist and Whig politician.

In 1841 he co-founded The Gardeners' Chronicle alongside Joseph Paxton, John Lindley and William Bradbury.

He was one of the most zealous promoters of the Great Exhibition of 1851 (of which Paxton was again an integral part), and a member of the executive committee.

Dilke was succeeded in the baronetcy by his eldest son, Charles, whose promising political career was destroyed by a well-publicised divorce case in the 1880s.
