The Danube Commission is an international intergovernmental organization, set up by the Convention regarding the regime of navigation on the Danube signed in Belgrade on 18 August 1948.

    As a result of the Danube River Conference of 1948, the river system was divided into three administrations — the regular River Commission (which had existed in one form or another since 1856), a bilateral Romania-USSR administration between Braila and the mouth of the Sulina channel, and a bilateral Romania-Yugoslavia administration at the Iron Gate. Both of the latter were technically under the control of the main commission, members of which were — at the beginning — Bulgaria, Czechoslovakia, Hungary, Romania, Ukraine, the USSR, and Yugoslavia.

    Members include representatives from Austria, Bulgaria, Croatia, Germany, Hungary, Moldova, Slovakia, Romania, Russia, Ukraine, and Serbia.

    The commission dates to the Paris Conferences of 1856, which established for the first time an international regime to safeguard free navigation on the Danube, and of 1921, which resurrected the international regime after the First World War.

    The primary tasks of the Danube Commission activity are provision and development of free navigation on the Danube for the commercial vessels flying the flag of all states in accordance with interests and sovereign rights of the member-states of the Belgrade Convention, as well as strengthening and development of economical and cultural relations of the said states among themselves and with the other countries.
