Salcette is a taluka (a unit of administration) of South Goa District in the Indian state of Goa. Its administrative and economic headquarters is Margao. It is largely coterminous with a region called Sashti, which comprised, by local tradition, sixty-six villages, hence the name. However, it also includes the taluka of Mormugao. There are six comunidades in Salcette namely—Raia, Margao, Loutolim, Curtorim, Verna and Benaulim, and Quelossim in Mormugao. Salcette is bound by the Sanguem talukas to the east, Arabian sea to west, Tiswadi and Ponda talukas to the north, Cancaona and Quepem talukas to the south.
According to the legends some 96 families known as Goud Saraswat Brahmins settled in the Konkan region, of which 66 settled in Salcette. Hence, the name Salcete, derived from the Sanskrit word Sassast meaning the number 66.
