The Porta Asinaria is a gate in the Aurelian Walls of Rome. Dominated by two protruding tower blocks and associated guard rooms, it was built between 270 and 273, at the same time as the Wall itself. It is through this gate that East Roman troops under General Belisarius entered the city in 536, reclaiming the city for the Byzantine Empire from the Ostrogoths.

By the 16th century it had become overwhelmed by traffic. A new breach in the walls was made nearby to create the Porta San Giovanni. At this point, the Porta Asinaria was closed to traffic.
