Nýdek (Polish: Nydekⓘ, German: Niedek) is a municipality and village in Frýdek-Místek District in the Moravian-Silesian Region of the Czech Republic.

The first written mention of Nýdek is from 1430, when Bolesław I, Duke of Cieszyn donated this territory to Nidek, who founded here a settlement.

[2] Politically the village belonged then to the Duchy of Teschen that was a fee of the Kingdom of Bohemia, which after 1526 became part of the Habsburg monarchy.

It was taken from them (as one from around fifty buildings) in the region by a special commission and given back to the Roman Catholic Church on 21 March 1654.

According to the censuses conducted in 1880–1910 the population of the municipality grew from 1,567 in 1880 to 1,747 in 1910 with a majority being native Polish-speakers (between 94.7% and 97.7%) accompanied by German-speaking (at most 74 or 4% in 1900) and Czech-speaking people (at most 17 or 0.9% in 1880).

Following the Munich Agreement, in October 1938 together with the Trans-Olza region it was annexed by Poland, administratively adjoined to Cieszyn County of Silesian Voivodeship.
