The Trzciniec culture is an Early and Middle Bronze Age (2400-1300 BCE) archaeological culture in Central-Eastern Europe, mainly Poland and parts of Lithuania. The material culture similarity and overall chronological contemporaneity with Komariv (Ukraine) and Sośnica (Belarus) cultures resulted in the definition of the Trzciniec-Komarów-Sośnica complex or, more recently, the Trzciniec Cultural Circle.
In Poland, the archaeological sites of the Trzciniec culture are found in Central, Southern, and Eastern Poland (Kuyavia, Lesser Poland, Mazovia, Podlachia, and Lublin Upland).
Trzciniec culture was firstly identified by Włodzimierz Antoniewicz, who named it "band pottery culture".
The term "Trzciniec culture" from the eponymous site Trzciniec near Opole Lubelskie was introduced by Józef Kostrzewski in 1930.
The first complete monograph of the Trzciniec culture was written by Aleksander Gardawski.
From a cultural-historical perspective, the origins of the Trzciniec culture are associated with three Corded Ware-related cultures: Mierzanowice, Strzyżów and Iwno.
In general, the Trzciniec culture was succeeded by the Lusatian culture.
The best known settlements of the Trzciniec culture were in Złota Pińczowska, Więcławice Świętokrzyskie, Goszyce, and west Bondyrz, close to the kurgans of Guciów. Some of these sites include important treasures containing materials such as ornamental gold and silver like in Stawiszyce and Rawa Mazowiecka.
Burial rite of the Trzciniec culture is characterized by regional preferences in using inhumation and cremation. Cases of inhumation were discovered in Wolica Nowa, in the form of kurgans. Evidence of kurgan inhumation have been found at Łubna-Jakusy, whereas kurgan cremation has been found at Guciów.
There is evidence for the use of chariots by the Trzciniec culture.
Mittnik et al. (2018) examined the remains of seven possible Trzciniec individuals buried in Turlojiškė, Lithuania between 2,100 BC and 600 BC.
