The Port Muhammad Bin Qasim (Urdu: ???? ??? ???? ?? ????), also known as Port Qasim, is a seaport in Karachi, Pakistan on the coastline of the Arabian Sea. It is Pakistan's second busiest port, handling about 35% of the nation's cargo (17 million tons per annum). Port Qasim and Karachi Port, the busiest port of country, together handle more than 90% of all external trade of Pakistan.
The port encompasses a total area of 12,000 acres wherein many industrial zones operate. In addition to the Pakistan Steel Mills (PSM) and KESC Bin Qasim Power Plant, around 80% of the Pakistan's automotive industry is located at Port Qasim. The port also provides direct waterfront access to two major nearby industrial areas, Export Processing Zone (Landhi) and Korangi Industrial Area. Approximately 60% of country's export and import is originated from these areas. Port Qasim is managed by Port Qasim Authority, a semi-autonomous government body.
In 1970s, as a part of Pakistani Prime Minister Zulfiqar Ali Bhutto's program for economic reforms and establishment of heavy industries, country’s first steel mill (Pakistan Steel Mills) was established near the southern city of Karachi. A purpose-built specialized port facility was also decided to be established for bulk handling of the massive imports of raw materials for steel production by the Pakistan Steel Mill of Pakistan. In addition to the future economic demands and strategic needs, this port was also meant to relieve congestion at the only seaport Karachi Port of the country. This port was named as Port Muhammad bin Qasim (also known as Port Qasim), after the Muslim general Muhammad bin Qasim who conquered Daybul and the coastal areas of Sindh around 712 CE.
Port Qasim is located, adjacent to the Bin Qasim town, in the southern part of Malir district, Karachi division, in Sindh. It is located in an old channel of the Indus River at a distance of 35 kilometers east of Karachi city center.
The geographic position of the Port Qasim places it in close proximity to major shipping routes. The approach to the port is along a 45-kilometre long Navigation Channel which provides safe navigation for vessels up to 75,000 metric tons deadweight (DWT).
Location of the Port Qasim makes it very well connected to the transportation infrastructure of the country. It is at distance of only 15 km from the national highway, providing direct access to the hinterland through road. Further 14kms of railway track inside the terminal links it to the national railway network through 6 railway tracks. Jinnah International Airport is also very near, at a distance of 22 km.
Port Qasim's residential area is a neighborhood of Bin Qasim Town of Karachi.
Integrated Cargo Container Control (IC3) facility
Country’s first Integrated Cargo Container Control (IC3) facility is being constructed at Port Qasim with a joint investment over US$ 8 million by Pakistan Customs and the US Customs and Border Protection.
Purpose of IC3 Programme is to enhance international maritime trade security considering post 9/11 security issues. The IC3 Program envisages joint screening of US-bound containerized cargo from Pakistan via live video link by the customs authorities of Pakistan and the US . The US Customs will not subject the screened cargo to re-examination on arrival at US ports. This facility will support for facilitation for the trade in terms of reduced time and cost for shipments.
Port Qasim is located on the northwest edge of the Indus Delta system. The system is characterized by long and narrow creeks, mud flats and Mangrove forests. Pakistan has one of the largest Mangrove ecosystem found in an arid climate. According to Flora of Pakistan (1972), eight species of Mangroves have been reported from Pakistan, however, only four continue to thrive. Several species of reptiles, birds, and terrestrial mammals inhabit the project area, wherever suitable habitats are found. These are constantly under threat due to increased shipping and industrial activities in the area.

As a part of this, initiative has been taken on conservation of Mangrove Ecosystem in the Korangi – Phitti Creek System, in the Indus Delta (including Port Qasim area). The project aims to conserve selected degraded mangrove forests in the Korangi – Phitti creek area through involvement of community, local schoolchildren and other stakeholders like Port Qasim Authority and the Government Forest Department.  
Tasman Oil Spill 2003 at Karachi Beach
In August 2003, the beach immediately west of the Port Qasim navigation channel was the scene of a major oil spillage when the Greek-registered Tasman Spirit ran aground. The environmental impact included large numbers of dead fish and turtles and a key mangrove forest, as well as dozens of people suffering nausea. At that time, it was feared that this incident will harm the coastal life in the Port Qasim area, however no major impact was observed near the Phitti Creek (waterway entrance to Port Qasim). 
Recently Port Qasim Authority (PQA) has announced that an implementation agreement is being signed for the development of a 'pollution free' Coal, Cement and Clinker Terminal (CCCT) worth $175 million with a handling capacity of up to eight million tons per year at port. This step would save the environment from irreparable damages and the health of the port workforce and nearby populations from serious respiratory diseases which would have been a serious threat if the powdery coal was handled in open/bulk on berths at port
