French India, formally the Établissements français dans l'Inde (English: French Settlements in India), was a French colony comprising five geographically separated enclaves on the Indian subcontinent that had initially been factories of the French East India Company. They were de facto incorporated into the Republic of India in 1950 and 1954. The enclaves were Pondichéry, Karikal, Yanaon on the Coromandel Coast, Mahé on the Malabar Coast and Chandernagor in Bengal. The French also possessed several loges ('lodges', tiny subsidiary trading stations) inside other towns, but after 1816, the British denied all French claims to these, which were not reoccupied.

By 1950, the total area measured 510 km (200 sq mi), of which 293 km (113 sq mi) belonged to the territory of Pondichéry. In 1936, the population of the colony totalled 298,851 inhabitants, of which 63% (187,870) lived in the territory of Pondichéry.

Puducherry, also known as Pondicherry, is a union territory of India, consisting of four small geographically unconnected districts. It was formed out of four territories of former French India, namely Pondichéry (now Puducherry), Karikal (Karaikal), Mahé and Yanaon (now Yanam), excluding Chandannagar (Chandernagore), and it is named after the largest district, Puducherry, which was also the capital of French India. Historically known as Pondicherry, the territory changed its official name to Puducherry on 1 October 2006.

The Union Territory of Puducherry lies in the southern part of the Indian Peninsula. The areas of Puducherry district and Karaikal district are bound by the state of Tamil Nadu, while Yanam district and Mahé district are enclosed by the states of Andhra Pradesh and Kerala, respectively. Puducherry is the 29th most populous of the 36 states and union territories of India, and the third most densely populated union territory. It has a gross domestic product (GDP) of ₹210 billion (US$2.5 billion) and ranks 25th in India.
