The Yenisei River is a massive river that runs through Russia, flowing from the eastern edge of the Siberian Plateau, and dividing into several branches before it flows into the Arctic Ocean. The river has several synonyms like Yenisey, Enisei, and Jenisej, which are all derived from the original name of the river in the native language of the region. The Yenisei River is the largest river system that flows into the Arctic Ocean and has many notable tributaries. Some of these tributaries include the Angara River, Podkamennaya Tunguska River, and Taseeva River. The Yenisei River plays a significant role in the livelihoods of many indigenous communities in Russia and is an important source of water and transportation.
