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

The name evolved from Trzenkowicze (1431, 1450) through Trzankowicze (1523, 1578), Strzankowicze (1571) into Trzanowicze beginning from 1610 (Trzanowiczyche), also the division to Upper (Horní/Górne/Ober) and Lower part (Dolní/Dolne/Nieder) of the village began in the 16th and 17th centuries.

[4] Politically Třanovice belonged then to the Duchy of Teschen, 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 24 March 1654.

According to the censuses conducted in 1880–1910, the population of the municipality dropped from 902 in 1880 to 875 in 1910 with a majority being native Polish-speakers (between 95.8% and 97.9%) accompanied by a small German-speaking minority (at most 38 or 4.2% in 1880) and Czech-speaking (at most 12 or 1.4% in 1910).

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.
