Agnes Elisabeth Guppy-Volckman (; 1838–1917) was a British spiritualist medium.

Career

She was born Agnes Elisabeth White in Horncastle, Lincolnshire not in Regent's Park, London. She was known as Agnes Nicholl when she became an orphan and she was adopted by her maternal grandfather William Grinsell Nicholl.

She became the wife of the spiritualist Samuel Guppy in 1867. After the death of Guppy in 1875, she married William Volckman.

Guppy was discovered by Fanny Sims who was the sister of Alfred Russel Wallace in the 1860s. Sims believed she had powers and she gave her first demonstration in 1866 at the Wallace's home. She was known for producing apports and materializations. Researcher Ronald Pearsall described the fraudulent techniques that Guppy used in her séances.

Molly Whittington-Egan has written a biography of Guppy titled Mrs Guppy Takes A Flight: A Scandal of Victorian Spiritualism.
