Fresach (Slovene: Breze) is a municipality in Villach-Land District, in the Austrian state of Carinthia.

The municipal area lies within the Nock Mountains (Mirnock massif) north of the Drava Valley.

A former prayer house erected in 1784 and preserved in its original condition is today the seat of a museum of the Lutheran diocese in Carinthia.

While the Ortenburg heritage had passed to the Austrian House of Habsburg, the majority of the local population turned Protestant in the early 16th century.

Though subjected to the stern measures of the Counter-Reformation under the rule of the Inner Austrian archduke (and later emperor) Ferdinand II (1590–1637), Fresach remained a centre of Crypto-protestantism.
