Kopychyntsi (Ukrainian: Копичинці, Polish: Kopyczyńce) is a small town in Ternopil Oblast, Ukraine. It has a population of 7,036 (census 2001). It is the birthplace of Ukrainian chess grandmaster Vassily Ivanchuk and Israeli politician Pinhas Lavon.
The town was first mentioned in 1340 as a village in the powiat of Trembowla. With time it grew to become a town within the Land of Halicz, itself part of Podole Voivodeship of Poland and then the Polish-Lithuanian Commonwealth. It was granted a city charter in 1564. In late 1648, during the Khmelnytsky Uprising, a combined Cossack and Tartar army under Asand Demko seized the town. However, following the Battle of Kopyczyńce of May 12, 1651, in which the enemy forces were defeated by hetman Marcin Kalinowski, it returned to Poland.
In the effect of the Treaty of Buchach of 1672 the town was ceded to Ottoman Empire, but it returned to Poland after the Treaty of Karlowitz of 1699. Following the Partitions of Poland it became part of Austrian Empire and was then seized by Napoleon Bonaparte who gave it to Russian Empire in the Treaty of Tilsit of 1807. Russian control however ended with the Congress of Vienna which awarded the area back to Austria. It shared the history of the surrounding lands of the Kingdom of Galicia and Lodomeria for the rest of 19th century.
Following World War I the area was disputed between Poland and the Ukrainian People's Republic (UNR) in what became known as the Polish-Ukrainian War. In June 1919, during the so-called Chortkiv offensive, the 1st Galician Corps of the UNR under Osyp Mykytko seized the town, but it was retaken by Polish forces under Józef Haller the following month. Following the treaty of Riga the town was officially restored to Poland. It was made a seat of a separate powiat within Tarnopol Voivodeship and a garrison town of a Border Protection Corps battalion Kopyczyńce.
Following the September Campaign of 1939 and the outbreak of World War II the town was occupied first by the Soviet Union and then Nazi Germany. After the war it was annexed by the USSR and since 1991 is part of independent Ukraine.
