Legnava (Hungarian: Hosszúvágás, German: Langenau, Rusyn: Леґнава) is a village and municipality in the Stará Ľubovňa District, Prešov Region in northern Slovakia.

At the end of the 16th century, Legnava was a medium-sized municipality with exclusively serf population mostly of Rusyn origin.

At that time, the inhabitants made their living mainly by hard labour, such as farming and construction.

[5] Before the establishment of independent Czechoslovakia in 1918, Legnava was part of Sáros County within the Kingdom of Hungary.

On 24 January 1945, the Red Army dislodged the Wehrmacht from Legnava and it was once again part of Czechoslovakia.
