Gaius Sulpicius Peticus was a prominent 4th-century BC Roman politician and general who served as consul five times and as dictator once. Sulpicius was a member of the gens Sulpicia, a prominent patrician family which had attained the consular dignity a great number of times following the foundation of the republic. However, the familial relationship between Sulpicius and other known contemporary members of the gens is unknown, with the only information about his heritage being that his father was named Marcus and his grandfather was named Quintus.
