伊洛瓦底江（缅甸语：ဧရာဝတီျမစ္，erawa.ti mrac，/ʔèjàwədì mjɪʔ/；英语原称Irrawaddy，现称Ayeyarwady），简称伊江，缅甸第一大河，长2,288公里，流域面积420,934平方公里。上游分两支，东支称恩梅开江（NmaiHka），起源于中国**察隅；西支称迈立开江（MaliHka），起源于缅甸克钦邦，在缅甸**以北会合后，从北到南贯穿缅甸，在仰光附近流入印度洋孟加拉湾。

伊洛瓦底江虽然并非缅甸最长的河流，但由于其航运及灌溉价值，故属该国最重要的河流。

The Irrawaddy River or Ayeyarwady River (Burmese: ဧရာဝတီမြစ်; MLCTS: erawa.ti mrac, pronounced: [ʔèjàwədì mjɪʔ], also spelt Ayeyarwaddy) is a river that flows from north to south through Myanmar. It is the country's largest river and most important commercial waterway. Originating from the confluence of the N'mai and Mali rivers, it flows relatively straight North-South before emptying through the Irrawaddy Delta into the Andaman Sea. Its drainage basin of about 255,081 square kilometres (98,487 sq mi) covers a large part of Burma. After Rudyard Kipling's poem, it is sometimes referred to as 'The Road to Mandalay'.
