The Roman Provincial Forum is an archaeological area in Mérida, Spain, built in the 1st century AD.

It was a public area of the Roman city of Emerita Augusta, founded in 25 BC.

The title of "provincial" came from the city's role as the capital of the province of Lusitania.

The temple received a massive marble decoration during the reign of the emperor Claudius.

The Forum consisted of a large square sided by a monumental portico, with a large temple in the center, which was accessed through the Arch of Trajan.
