Dadra and Nagar Haveli is a Union Territory in Western India. Nagar Haveli is wedged between Maharashtra and Gujarat, whereas Dadra is an enclave 1 km NW, surrounded by Gujarat. The shared capital is Silvassa. The larger part spans a roughly c-shaped area up-river from the city of Daman on the coast, at the centre of which, and thus outside the territory, is the Madhuban reservoir.

Nagar Haveli (Portuguese: Nagar-Aveli) is the larger pocket in the Indian Union Territory of Dadra and Nagar Haveli. It is surrounded by the Indian states of Gujarat and Maharashtra.
