Loka Brunn is a spa town located in Hällefors Municipality in Örebro County, Sweden, south of Grythyttan, and north of Karlskoga, at an isthmus-strip between the southern shore of Lake Norra Loken and the northern shore of Lake Södra Loken.

[4] Granted mineral rights in 1720, by Conrad Ribbing, governor of Örebro County, in the historical province Västmanland, near the border of Värmland, surrounded by conifer forests,[6] and described by Carl Linnaeus in 1746.

Established as a meeting spot for 18th-century Swedish politicians, the Caps party historically preferred Loka Brunn over Medevi, which instead was favored by the rival Hats.

[10] Additionally, during the 19th century, individuals suffering from rheumatic disorders sought treatment at Loka Brunn.

After the displacement of individuals during World War II, Danish and Norwegian groups were relocated and housed at Loka Brunn.
