The Aldan (Russian: Алдан) is the second-longest, right tributary of the Lena in the Sakha Republic in eastern Siberia.^[1] The river is 2,273 kilometres (1,412 mi) long, of which around 1,600 kilometres (990 mi) is navigable. It has a drainage basin of 729,000 square kilometres (281,000 sq mi).^[2]

The river was part of the River Route to Okhotsk. In 1639 Ivan Moskvitin ascended the rivers Aldan and Maya and crossed to the Ulya to reach the Sea of Okhotsk.

Its basin is known for gold and for Cambrian fossils.

Course[]

The Aldan rises in the Stanovoy Mountains southwest of Neryungri. It flows roughly in a northeast/ ENE direction south of the Lena Plateau across the Aldan Highlands, where it forms the northern border of the Sunnagyn Range. Then it flows past Aldan and through Tommot, Ust-Maya, Eldikan and Khandyga before turning northwest flanking the southern slopes of the Verkhoyansk Range and joining the Lena near Batamay.^[3]

The river's main tributaries are the Timpton, Uchur, Maya, , Allakh-Yun, Khanda, Tyry, , Tompo, , Baray, Tukulan, Kele and Tumara from the right, and the Amedichi, , Yungyuele, , , , Amga, Tatta and from the left.^[4]
