Which peninsula in Malaysia contains the historic city of Malacca?

The Malaysian peninsula containing the historic city of Malacca is the Malay Peninsula.

The Malay Peninsula runs north–south through mainland Southeast Asia and includes Peninsular Malaysia, southern Thailand and Myanmar’s southernmost tip. Malacca, also spelled Melaka, lies on the peninsula’s southwestern coast beside the Strait of Malacca, one of the world’s most important maritime passages between the Indian Ocean and the South China Sea.

The city rose to prominence under the Malacca Sultanate, founded around the beginning of the 15th century. Its sheltered harbour attracted merchants from China, India, Arabia and other parts of Southeast Asia. Portugal captured Malacca in 1511, the Dutch took it in the 17th century, and it later became part of Britain’s Straits Settlements, leaving a strongly layered architectural and cultural heritage.

The name can cause confusion because Malacca is both a Malaysian state and its historic capital, Malacca City. The peninsula itself is much larger and extends beyond Malaysia into Thailand and Myanmar. Malacca City, together with George Town, became a UNESCO World Heritage site in 2008.
