Rybnik (Polish pronunciation: AUDPl-Rybnik.ogg'rybńik; Rybńik) is a city in southern Poland, in the Silesian Voivodeship, around 38 km (24 mi) southwest of Katowice, the region's capital, and around 19 km (11 miles) from the Czech border. It is one of the major cities of the Upper Silesian metropolitan area with a population of 5.3 million and the main city of the so-called Subregion Zachodni, previously also known as the Rybnik Coal Area. With a population of 135,994 as of January 1, 2022, it is the 25th most-populous city in Poland.
Rybnik is the center of commerce, business, transportation and culture for the southwestern part of the Silesian Voivodeship, a consolidated city-county and the seat of a separate suburban Rybnik county. Rybnik is particularly recognized for its contributions to music, with the Szafrankowie School of Music musicians such as Henryk Górecki or Lidia Grychtołówna, among others. It is also a seat of the Rybnik Philharmonic Orchestra.
The name Rybnik derives from an old Slavic word rybnik, meaning a pond (Czech language still uses it, while in Polish the modern word is staw), which was located in the place of the current market square. In the middle ages, three settlements merged into one town, with a German-law location dating back to 1308. Fishing, trade and artistry were the main industries. Rybnik's development accelerated in late 19th century upon discovery of rich coal fields, and continued until the 1980s. Since the 1990s, the city attempts to diversify its economy with commerce, health care and business industries.
The city's name derives from the Proto-Slavic word for "fish" (ryba) and meant "fishpond" in the Old Polish language. The name highlights the importance of fish farming for the city's economy in the Middle Ages, which is reflected in its coat of arms until this day.
The city's origins can be traced back into the 9th and 10th century, when three Slavic settlements existed on Rybnik's present-day territory which eventually merged to form one town.
