Nardò (Latin: Neritum or Neretum; Messapic: Nareton) is a town and comune in the southern Italian region of Apulia, in the Province of Lecce.

Lies on a lowland area placed at south-west of its Province, its border includes part of the Ionian coast of Salento.

For centuries, it had been one of the central cities of the Byzantine Empire, until 1497, when the ducal House of Acquaviva acquired it under their domain. During those years it became the main cultural hotspot of Salento, seat of many Universities, Academies, literary and philosophical studies: it was given the name of Nuoua Atene litterarum.

With almost 32.000 inhabitants and 190 squared kilometres of land, it is the second largest and most populated city among those in the Province, right after Lecce, and also one of the most culturally active towns of Salento. The Old Town is particularly rich with palaces, churches, chapels and other architectural details shaped accordingly to the principles of Lecce's Baroque style. Indeed, the city is a significant example of this art movement along with Gallipoli and Lecce.

The stretch of coast wet by the Ionian Sea is split into small inhabited fractions such as Santa Caterina, Santa Maria al Bagno, Sant'Isidoro and Porto Selvaggio. The latter is a Nature Reserve created by a reforestation that happened during 1950s.
