Extraliga ragby XV

The Extraliga rugby XV is a rugby club competition played in the Czech Republic and is the top level of rugby in the country. There is a promotion-relegation process between the Extraliga ragby and the 1. Liga ragby XV. The league used to be known as KB Extraliga due to sponsorship by Komerční banka (KB) which lasted until the 2014/15 season.

The season usually runs from September to May, although in the 2008 season, it was only from August through November 2008. Since 2008 the final has been played at the Synot Tip Arena in Prague.

RC Mountfield Říčany are the current champions.

History
The league was first played in 1993, with Vyškov as the first champions. Prior to the foundation of the league, clubs competed in the Czechoslovak Championship.

It became known under the KB Extraliga name in 2003, when KB started sponsoring the Czech Rugby Union, as well as the national teams and leagues. For the 2016/17 season the name changed to Extraliga ragby in line with the Czech rugby union league system restructure. In 2021 the name changed to Extraliga ragby XV.
