The Nile River (Arabic: النيل‎, Egyptian Arabic en-Nīl, Standard Arabic an-Nīl; Coptic: ⲫⲓⲁⲣⲱ, P(h)iaro; Ancient EgyptianḤ'pī and Jtrw; Biblical Hebrew: הַיְאוֹר‬, Ha-Ye'or or הַשִׁיחוֹר‬, Ha-Shiḥor) is a major north-flowing river in northeastern Africa, and is commonly regarded as the longest river in the world, though some sources cite the Amazon River as the longest. The Nile, which is 6,853 km (4,258 miles) long, is an "international" river as its drainage basin covers eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Republic of the Sudan and Egypt. In particular, the Nile is the primary water source of Egypt and Sudan.

The Nile River has two major tributaries, the White Nile and Blue Nile. The White Nile is considered to be the headwaters and primary stream of the Nile itself. The Blue Nile, however, is the source of most of the water and silt. The White Nile is longer and rises in the Great Lakes region of central Africa, with the most distant source still undetermined but located in either Rwanda or Burundi. It flows north through Tanzania, Lake Victoria, Uganda and South Sudan. The Blue Nile (Amharic: ዓባይ, ʿĀbay) begins at Lake Tana in Ethiopia and flows into Sudan from the southeast. The two rivers meet just north of the Sudanese capital of Khartoum.

The northern section of the river flows north almost entirely through the Sudanese desert to Egypt, then ends in a large delta and flows into the Mediterranean Sea. Egyptian civilization and Sudanese kingdoms have depended on the river since ancient times. Most of the population and cities of Egypt lie along those parts of the Nile valley north of Aswan, and nearly all the cultural and historical sites of Ancient Egypt are found along riverbanks.

In the ancient Egyptian language, the Nile is called Ḥ'pī or Iteru (Hapy), meaning "river". In Coptic, the word ⲫⲓⲁⲣⲱ, pronounced piaro (Sahidic) or phiaro (Bohairic), means "the river" (lit. p(h).iar-o "the.canal-great"), and comes from the same ancient name.

The English name Nile and the Arabic names en-Nîl and an-Nîl both derive from the Latin Nilus and the Ancient Greek Νεῖλος. Beyond that, however, the etymology is disputed. Hesiod at his Theogony refers that Nilus (Νεῖλος) was one of the Potamoi (river gods), son of Oceanus and Tethys. Another possible etymology derives it from a Semitic Nahal, meaning "river". The standard English names "White Nile" and "Blue Nile", to refer to the river's source, derive from Arabic names formerly applied only to the Sudanese stretches which meet at Khartoum.

Above Khartoum, the Nile River is also known as the White Nile, a term also used in a limited sense to describe the section between Lake No and Khartoum. At Khartoum the river is joined by the Blue Nile. The White Nile starts in equatorial East Africa, and the Blue Nile begins in Ethiopia. Both branches are on the western flanks of the East African Rift.
