William John Charles Möens (12 August 1833 – 6 January 1904) was an English writer, known as an antiquarian dealing with Huguenot topics.

He was privately educated, began a career on the Stock Exchange, but soon retired to a house which he had bought at Boldre in Hampshire, taking up yachting, and later antiquarian researches.

By his will he divided his library between the Hampshire county council and the French Protestant Hospital, Victoria Park, London.

In 1869 he sailed his steam yacht Cicada from Lymington up the River Rhine to Strassburg, and by French canals to Paris and Le Havre.
