Guillaume Rufin (; born 26 May 1990) is a French former professional tennis player. His highest singles ranking is World No. 81, achieved in September 2013.
Rufin achieved another landmark in his young career on 25 October 2009, when he won the Florianópolis Challenger title in Brazil, beating Pere Riba in the final, 6–4, 3–6, 6–3.
Rufin received a wildcard into the 2010 US Open and defeated Leonardo Mayer in four sets before losing to Paul-Henri Mathieu in the second round.
