The Roman Theatre of Lillebonne is an ancient entertainment venue located in the former city of Juliobona, now Lillebonne, in France.

Constructed in the 1st century AD by utilizing a natural hillside for support, the structure was rebuilt and enlarged during the 2nd and 3rd centuries before being repurposed as a fortress at the end of the 3rd century. Despite research interruptions lasting several decades, the theatre has been the subject of regular excavations since the early 19th century. As of the 21st century, only the stage area—currently covered by a modern road—remains unexcavated. It was officially designated as a monument historique in the original 1840 protection list.
