Saints Sergius and Bacchus (also Serge and Bacchus or Σέργιος και Βάκχος), were third century Roman soldiers who are commemorated as martyrs by the Roman Catholic, Eastern Orthodox and Oriental Orthodox churches. Their feast day is October 7.

According to their hagiography, Sergius and Bacchus were officers in Emperor Galerius' army (also see Arch of Galerius at Thessaloniki, Greece, the city where Galerius carried out most of his administrative actions), and were held high in his favor until they were exposed as secret Christians. They were then severely punished, with Bacchus dying during torture, and Sergius eventually beheaded in Resafa, Syria. However, due to its inconsistencies and historical anachronisms, the hagiography is considered ahistorical.
