Historically, the Lena River has played a significant role in the exploration and colonization of Siberia. Its banks have witnessed the passage of indigenous peoples, Russian settlers, and various expeditions throughout the centuries.

The word "Lena" is derived from the name of the river itself, which is the Lena River. The etymology of "Lena" can be traced back to the indigenous Sakha (Yakut) people who inhabit the region through which the river flows. In the Sakha language, the river is called "Элюэнэ" (Elyuene), which means "big river" or "great river". Over time, the name "Elyuene" was transliterated into Russian as "Лена" (Lena) and became the commonly used name for the river.
