Jezersko (official name: "Občina Jezersko", German: "Gemeinde Seeland") is a municipality in Slovenia. It lies in the north of the country, just a few kilometres south of the Seebergsattel border crossing between Slovenia and Austria. The main activities are tourism, cattle breeding and forestry.

The name of the area is derived from a glacial lake at the settlement of Zgornje Jezersko that dried out during the 15th century, thus the German name "Seelandt" (literally 'lake land', first recorded in 1496), and its Slovenian equivalent "Jezersko", which came into use at the end of the 19th century. A document from 1391 mentions the church of "St. Oswald by the Lake" ("Sv. Ožbolt pri Jezeru"). Lake Planšar (Sln. "Planšarsko jezero") in Zgornje Jezersko is an artificial lake created after the Second World War.

The village was part of the Duchy of Carinthia before 1918 and since then forms part of the region of Koroška.
