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).

In historical records the village was first mentioned in 1266. Before the establishment of independent Czechoslovakia in 1918, it was part of Turóc County within the Kingdom of Hungary. From 1939 to 1945, it was part of the Slovak Republic.

In the 19th century the chateau got under control of Franklins. The first member of the Franklins’ clan was Benjamin Franklin, an illegitimate son of Dionyz Justh and great-granddaughter of Benjamin Franklin.

The municipality lies at an altitude of 515 metres and covers an area of 42.172 km. It has a population of about 826 people.

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. It is expected to have a yearly output of 160,000 kW. The construction, which cost 5 million Slovak crowns, should be profitable after five years of operation. Three more similar power stations are planned to be finished by the end of 2007 in Necpaly.
