The 'Ayeyarwady River' or 'Irrawaddy River' () is a river that flows through
Burma (Myanmar). It is Myanmar's largest river (about 1350 miles or 2170 km long) and its most important commercial
waterway, with a
drainage area of about 158,700 square miles (411,000 km²).
The Ayeyarwaddy River starts in
Kachin State, at the confluence of the '
Mali Hka' and '
N'Mai Hka' rivers. The western Mali Hka branch arises from the end of the southern
Himalayas, north of
Putao, and (like the main river) is called Nam Kiu in the
Shan language.

Built in 1934, the Ava Bridge near
Sagaing,
Myanmar, was the only bridge over the Ayeyarwady (Irrawaddy) River until 1998.
The Ayeyarwaddy River bisects the country from north to south and empties through a nine-armed
delta into the
Indian Ocean. In colonial times, before railways and automobiles, the river was known as the "Road to
Mandalay". Although navigable by large vessels to
Myitkyina for a distance over 1600 km from the ocean, the river is also full of sandbanks and islands, making such navigation difficult. For many years, the only bridge built to cross the Ayeyarwady River was the Inwa Bridge.
The names Irrawaddy and Ayeyarwady are believed to have derived either from the
Sanskrit name
Iravati, a sacred river and minor goddess in Indian mythology, or from her son
Airavata, the elephant mount of
Indra.
The Irrawaddy gives its name to a
dolphin, the
Irrawaddy dolphin (''Orcaella brevistosus''), which is found in the river. Though sometimes called the Irrawaddy River Dolphin, it is not a true
river dolphin, since it is also found at sea.
