Lake Baikal (/bˈkɑːl, -ˈkæl/ by-KAHL, -⁠KAL;[3] Russian: Озеро Байкал, romanizedOzero Baykal [ˈozʲɪrə bɐjˈkaɫ]; Buryat: Байгал далай, romanized: Baigal dalai[4]) is the deepest rift lake in the world. It is situated in southern Siberia, Russia between the federal subjects of Irkutsk Oblast to the northwest and the Republic of Buryatia to the southeast.

At 31,722 km2 (12,248 sq mi)—slightly larger than Belgium—Lake Baikal is the world's seventh-largest lake by surface area,[5] as well as the second largest lake in Eurasia after the Caspian Sea. However, because it is also the deepest lake,[6] with a maximum depth of 1,642 metres (5,387 feet; 898 fathoms),[1] Lake Baikal is the world's largest freshwater lake by volume, containing 23,615.39 km3 (5,670 cu mi) of water[1] or 22–23% of the world's fresh surface water,[7][8] more than all of the North American Great Lakes combined.[9] It is also the world's oldest lake[10] at 25–30 million years,[11][12] and among the clearest.[13]

Lake Baikal is home to thousands of species of plants and animals, many of them endemic to the region. It is also home to Buryat tribes, who raise goats, camels, cattle, sheep, and horses[14] on the eastern side of the lake,[15] where the mean temperature varies from a winter minimum of −19 °C (−2 °F) to a summer maximum of 14 °C (57 °F).[16] The region to the east of Lake Baikal is referred to as Transbaikalia or as the Transbaikal,[17] and the loosely defined region around the lake itself is sometimes known as Baikalia. UNESCO declared Baikal a World Heritage Site in 1996.[18]
