Gualdo Tadino () is a town in the province of Perugia in northeastern Umbria, on the lower flanks of Monte Penna, a mountain of the Apennines. It is northeast of Perugia.

Etymology

The name Gualdo derives from the Lombardic term wald, meaning a wooded place.

In Roman times, Pliny the Elder placed Tadinum in the Regio VI Umbria.

Early Middle Ages

In 545, during the Gothic War, Totila encamped at Tadinum.

In the 19th century the city had a population of 6,422 inhabitants, of whom 2,364 lived within the town and 4,058 in the surrounding countryside.

In 2021, 1,426 people lived in rural dispersed dwellings not assigned to any named locality.

The first written records of ceramic supply date to the 14th century, with forms and decorations recalling types found in the areas of Gubbio, Orvieto, and Deruta. In the second half of the 15th century, documents attest to the recognized quality of local maiolica, including authorization in 1456 for the sale of ceramics such as olle and pignatte in the markets of Gubbio.

The settlement at Colle I Mori spans a chronological range from the late 6th century to the 3rd–2nd century BCE. It constitutes a rare example of proto-urban organization in Umbrian territory.
