Zlatno (Hungarian: Zlatnó or Zlatnótelep) is a village and municipality in the Poltár District in the Banská Bystrica Region of Slovakia. In 1998 it became a self-administered village, before it was a part of Kokava nad Rimavicou.

Before the establishment of independent Czechoslovakia in 1918, Zlatno was part of Nógrád County within the Kingdom of Hungary. From 1939 to 1945, it was part of the Slovak Republic.

Production of glass started in the village in 1833. Products had been transported to several world exhibitions. In the middle of 19th century came to Zlatno Leo Valentin Pantoček. He invented the way how to produce the glass money. Later this technique was named as hyaloplastics. In 1856 followed the invention of iris glass. A lot of production had been exported to United Kingdom and United States. In Zlatno had been a glasswork museum, which, however, ceased to exist. The glass factory stopped its production in 2003. However, several private companies continue in glass production.
