Marcus Aufidius Lurco was a Roman magistrate and a member of the gens Aufidii.

Lurco held a high office at Rome. In 61 BC, he was a Tribune of the Plebs. During his time as Tribune, he was the author of the Lex Aufidia de Ambitu. The Lex Aufidia was a law concerning the Roman assemblies or Comitia. If a candidate, promised and paid money to a tribe at the Comitia, he should pay yearly 3,000 sesterces during his life. However, if the candidate, merely promised and did not pay, the candidate should be exempt. This caused a witted argument between Lurco and Publius Clodius Pulcher.

Lurco in 59 BC, was one of the witnesses called for the defence at the impeachment of Lucius Valerius Flaccus. Between 52 BC-51 BC, Lurco prosecuted and procured for the acts of violence and the conviction of Sextus Clodius Pulcher for bringing the corpse of Publius Clodius Pulcher into the Curia Julia.

Lurco was the first person in Rome to fatten peacocks for sale and from this he became wealthy.
