The
Amu Darya (,

Amudaryo; ; ,
da Āmú Sínd; ,
Oxos; ,
Vakṣu), also called the
Amu River and historically known by its
Latin name,
Oxus, is a major river in
Central Asia. It is formed by the junction of the
Vakhsh and
Panj rivers, at
Qal`eh-ye Panjeh in
Afghanistan, and flows from there north-westwards into what remains of the
Aral Sea. In ancient times, the river was regarded as the boundary between
Greater Iran and
Turan.
