The Malay Peninsula or Thai-Malay Peninsula (Malay: Semenanjung Tanah Melayu; سمننجوڠ تانه ملايو, Thai: คาบสมุทรมลายู) is a peninsula in Southeast Asia. The land mass runs approximately north-south and, at its terminus, is the southern-most point of the Asian mainland. The area contains the southernmost tip of Burma, Peninsular Malaysia, Singapore, and Southern Thailand.
The Titiwangsa Mountains are part of the Tenasserim Hills system, and form the backbone of the Peninsula. They form the southernmost section of the central cordillera which runs from Tibet through the Kra Isthmus (the Peninsula's narrowest point) into the Malay peninsula. The Strait of Malacca separates the Malay Peninsula from the Indonesian island of Sumatra while the south coast is separated from the island of Singapore by the Straits of Johor.
The Malay term Tanah Melayu (literally: 'The Malay Land') is generally used by the Malays and occasionally used in political discourse to describe uniting all ethnic Malay people on the peninsula under one Malay nation, although this ambition was largely realised with the creation of Malaysia.
