Kalná Roztoka (Hungarian: Kálnarosztoka, Rusyn: Кална Розтока) is a village and municipality in Snina District in the Prešov Region of north-eastern Slovakia.

In historical records, the village was first mentioned around 1554 to 1568. In 1877, the villages of Kalná and Roztoka came together to form the current village. Before the establishment of independent Czechoslovakia in 1918, Kalná Roztoka was part of Zemplén County within the Kingdom of Hungary. In 1939, it was for a short time part of the Slovak Republic. As a result of the Slovak–Hungarian War of 1939, it was from 1939 to 1944 again part of Hungary. In the autumn of 1944, the Red Army entered Kalná Roztoka and it was once again part of Czechoslovakia.

The village is known for its wooden church, which dates back to the early-mid 18th century. The church is constructed of wood, but has white-washed clay plaster on the exterior walls, thus giving the appearance of a masonry building. It is the only Lemko Rusyn church of this sort.

The municipality lies at an altitude of 300 metres (980 ft) and covers an area of 22.759 km (8.787 sq mi). It has a population of about 615.
