The West Coast of Peninsular Malaysia (Malay:Pantai Barat Semenanjung Malaysia) includes states which have their coastlines along the Straits of Malacca. This part of the peninsular is more urban and developed than the more Malay, Muslim and rural East Coast. As a result, the terms West Coast and East Coast tend to mean more than a geographical description of the states. The capital of Malaysia, Kuala Lumpur, and the new administrative centre of Putrajaya are located in this region.
