The unique natural conditions where Lagan is situated seem as if specially designed for hunting and fishing. There are different versions about the origin of the name "Lagan". According to one of them, the word is translated from the Mongolian language as "muddy." Another option is that the name comes from the name of one Kalmykian man Lag, who once grazed cattle on the island of Lagan. It is also possible that the name comes from the nature of the local soil, mainly sandy, swampy and of lagoonal.

On the territory of the Northern Caspian since the ancient times different tribes lived: the Scythians, the Sarmatians, the Huns, the Magyars, the Cuman people, the Tatar-Mongols, etc. Later it was settled by the Oirats (the Kalmyks). Lagan was founded in 1870 as a settlement of displaced peasants from central Russia on Lagan island. In search of free land and work here the peasants come from Astrakhan, Saratov, Penza, Voronezh, Simbirsk, Kazan and other provinces. Since 1936 Lagan has been a working settlement. After the eviction of the Kalmyk people and the elimination of the autonomous republic in 1944 a national name Lagan was replaced by Caspiyskiy.

It is preserved when restoring the Kalmyk autonomy in 1957. Status of the Caspian city it has since 1963. In 1991, the former name - Lagan - was returned to the city. In 2000, the city of Lagan among 35 other Russian cities has become a grant holder of the "Open Society" (Soros Foundation) under the program "Small cities of Russia". In 2002, Lagan was visited by the famous traveler Fyodor Konyukhov. Part of the route of the expedition "Following the Silk Road," in which he participated, took place on the territory of the Lagan area.
