Port Klang is the principal port in Selangor, a state of Malaysia. It also serves as the port for the Klang Valley, Malaysia's most developed region where the capital Kuala Lumpur is located.

There is nothing much to bring a traveller to Port Klang except for the ferry links to Dumai and Tanjung Balai Asahan, both in Sumatra, Indonesia. Port Klang and Klang town is very popular as Food Haven for locals and dynamic entreprenuer business. The largest AEON shopping center in Southeast Asia is operational in 2008 and the largest Wholesale city called GM Klang is projected to commence its wholesale business for products such as fashion apparels, all kinds of bags, ladies accessories, watches, building materials, electrical and electronic devices and more by the mid of 2009. Like most port cities, Port Klang has a seedy feel to it and most of its buildings and structures are maritime-related, such as warehouses, storage tanks and offices.

In maritime terms, Port Klang actually consists of three distinct ports. The port nearest to Port Klang town is known as the South Port. There is also a North Port and the newly developed Westport located on an island just off the coast of Port Klang.
