James Stanislaus Bell (Adyghe: Якъуб-Бий) (9 January 1797 – 10 March 1858) was a British adventurer and writer who participated in the Russo-Circassian War on the side of the Circassians.

Bell was involved in a case against Russia known as the Mission of the Vixen. He was the owner of a ship that was detained by the Russian coast guard, so he remained in Circassia from 1838 to 1839. Under the guise of establishing commercial relations, he was aiding the resistance of the Circassians against the Russian Empire. He compiled a description of the local peoples and a map of Circassia. He published his memoirs in 1840.
