Ammaia is a Roman city in central-eastern Portugal (near Marvao), which was founded at the end of the 1st century BCE. The city covered an area of 25 ha, was inhabited by about 2,000 people and was a prosperous city in the province of Lusitania. The city was founded on the left bank of the Sever River. The land in this area is fertile, which guaranteed good yields; moreover, residents had very good access to drinking water.

During the reign of Emperor Claudius, Ammaia received the status of civitas; between the first and the middle of the second century CE in turn, it received the status of municipium. The city was abandoned in the first half of the 6th century CE.
