Horní Lomná (Polish: Łomna Górnaⓘ, German: Ober Lomna) is a municipality and village in Frýdek-Místek District in the Moravian-Silesian Region of the Czech Republic.

The name of the village is borrowed from an older name of the Lomná river (mentioned in 1592 as Lomny), which itself is derived from the words lom ('turn', 'bend').

The highest point is the Velký Polom mountain at 1,067 m (3,501 ft) above sea level, located on the Czech-Slovak border.

There also several small-scale protected areas; the most notable is the Mionší National Nature Reserve, which is among the largest old-growth forests in the Czech Republic.

[3] The settlement on the territory of the village in the Lomná river valley in the Moravian-Silesian Beskids began in the middle of the 17th century.

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.
