Lake Lemuria (Ukrainian: Лемурійське озеро, romanized: Lemuriiske ozero), also known as Pink Lake, is a small lake in the western part of Syvash Bay in the Kherson region of Ukraine. It is located near the villages of Hryhorivka [uk] and Novovolodymyrivka [uk], Lemuria lake has pink water due to an algae which produces large amounts of beta-carotene. Lake Lemuria is a healing resort of international importance.

The salinity of the lake water reaches 270 – 300 grams of salt per liter of water.

The origins of the lake are disputed. According to one theory, on 26 August 1969, a Soviet bomber crashed on the shores of Syvash. Rescuers allegedly breached salty aquifers while digging to a depth of 18 meters to collect the remains of the bomber. The lake was later formed when underground water filled the excavation. Residents of the surrounding villages named the lake "Yama" and often went for a swim for fun. After some time, stories about the healing properties of the salt water of the lake began to spread. This allowed starting the development of green tourism in this region. Supporters of Helena Blavatsky's esoteric ideas named the lake, as a reference to the mythical continent Lemuria.

The pink colour of the reservoir is due to unicellular algae Dunaliella saline, which contain beta-carotene to protect it from long-term UV radiation. The hotter the summer, the more water evaporates from the lake and the brine gets a more saturated colour. While retreating, the water leaves a large amount of salt crystals on the shore. In places, salt crystals get lost, forming "stalagmites". The white shore and the pink lake give this part of Kherson region a very distinctive appearance.

The mud of this lake was certified in 2005 and approved for use as a therapeutic and cosmetic product. The mud of the lake is included in the program of insurance medicine in Germany.
