The Theatre of Pompey (, ) was a structure in Ancient Rome built during the later part of the Roman Republican era. It was completed in seven years, and was dedicated early in 55 BC before the structure was fully completed. It was one of the first permanent (non-wooden) theatres in Rome. The building itself was a part of a multi-use complex that included a large quadriporticus directly behind the scaenae frons. Enclosed by the large columned porticos was an expansive garden complex of fountains and statues. Along the stretch of covered arcade were rooms dedicated to the exposition of art and other works collected by Gnaeus Pompeius Magnus (English: "Pompey the Great") during his campaigns.
