The Pillar of the Boatmen (French: Pilier des nautes) is a monumental Roman column erected in Lutetia (modern Paris) in honour of Jupiter by the guild of boatmen in the 1st century AD. It is the oldest monument in Paris and is one of the earliest pieces of representational Gallo-Roman art to carry a written inscription. The Roman name for the monument is Nautae Parisiaci (the sailors of the Parisii, who were a tribe of Gauls). It was found re-used in the 4th century city wall on the Île de la Cité and is now displayed in the frigidarium of the Thermes de Cluny.
