Necpaly (Hungarian: Necpál) is a village and municipality in Martin District in the Žilina Region of northern Slovakia.

The name is derived from an adjective necpalý referring to a low density village (Slovak: cpať - to push, to overcrowd, a negative verb necpať).

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

In summer 2007 the first municipal water power station in Slovakia started generating electricity which is in part used for the municipal office building needs and public lighting and in part supplied to the public grid.

The construction, which cost 5 million Slovak crowns, should be profitable after five years of operation.
