The Maritime and Port Authority of Singapore (MPA) was established on 2 February 1996 by the MPA Act of 1996 through the merger of the Marine Department (which was under the then Ministry of Communications), National Maritime Board and the Regulatory departments of the former Port of Singapore Authority (PSA).

This includes vessel traffic and navigational safety and security, through regulation on operational efficiency and on the environment.

Its aims include attracting a core group of shipowners and operators to establish operations in Singapore, broadening the breadth and depth of maritime ancillary services offered, and improving the business environment for the maritime industry.

As the National Sea Transport Representative, the MPA safeguards Singapore's maritime/port interests in the international arena.

This extends to being the government's advisor on matters relating to sea transport, and maritime/port services and facilities.
