Fulvius (fem. Fulvia) was the nomen of the gens Fulvia, a plebeian gens of ancient Rome that originally came from Tusculum.

Lucius Fulvius Curvus , the first of the gens, was consul in 322 BC, and under the patronage of the Fabii, many more Fulvii played an important role in the state. Major families included the Fulvii Flacci and the Fulvii Nobiliores.
