A Famosa (Malay: Kota A Famosa; "The Famous" in Portuguese) is a Portuguese fortress located in Malacca, Malaysia. It is among the oldest surviving European architectural remains in south east Asia. The Porta de Santiago, a small gate house, is the only part of the fortress which still remains today.

The name is often mispronounced /eɪ/ Famosa, even among Malaysians, as though the Portuguese definite article a were the English letter A. A more authentic pronunciation would be /ɑː/ Famosa.

In the 17th century, the Dutch built a fort in an effort to control the Perak tin trade known as the Dutch Fort. In 1874, it was the location of a historical treaty between the British government and a contender for the Perak throne (the Pangkor Treaty), which began the British colonial domination of the Malay Peninsula. The old British name for the Pangkor Island group was the Dindings.

Pangkor Island has a land area of 18km and is 3.5 kilometres (2.2 mi) from Peninsular Malaysia. The interior of the island is forested and is home to 65 reptile species, 17 amphibian species, and 82 total herpetofaunal species.
