Senan is a village and municipality in the comarca of Conca de Barberà, in the province of Tarragona, Catalonia, Spain. It is a small settlement, with a population recorded at 47.
The municipality lies within the Garrigues geographic region, but in the 1936 comarcal revision it was included in Conca de Barberà rather than in Garrigues. This places Senan among the localities whose administrative comarca differs from the natural or historical region to which they are commonly assigned.
