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

Before the establishment of independent Czechoslovakia in 1918, Kalná Roztoka was part of Zemplén County within the Kingdom of Hungary.

In the autumn of 1944, the Red Army entered Kalná Roztoka and it was once again part of Czechoslovakia.

The church is constructed of wood, but has white-washed clay plaster on the exterior walls, thus giving the appearance of a masonry building.

The municipality lies at an altitude of 300 metres (980 ft) and covers an area of 22.759 km2 (8.787 sq mi).
