Charles Richard Fox (1796 - 1873) was the illegitimate son of Henry Richard Vassall-Fox, 3rd Baron Holland, through a liaison with Lady Webster, whom Lord Holland would later marry.

After some service in the Navy, Fox entered the Grenadiers, and was known in later life as a collector of Greek coins. His collection was bought for the royal museum of Berlin when he died in 1873. He married Lady Mary Fitzclarence, a daughter of William IV by Mrs Jordan.
