Beckov (Hungarian: Beckó, German: Beckow) is a village and municipality in the Nové Mesto nad Váhom District in the Trenčín Region of western Slovakia.

Mihály de genere Bána, royal equerry, who was the forefather of the Cseszneky family, performed several heroic deeds against the Mongolian invaders of Hungary (during the invasion in 1241–42) and for his bravery in 1241 King Béla IV appointed him Count (comes) of Beckó.

Before the establishment of independent Czechoslovakia in 1918, Beckov was part of Trencsén County within the Kingdom of Hungary.

The village, which used to be a town, was fortified by a mighty wall, large parts of which are still preserved.
