The Topklasse (known until 2010 as the Hoofdklasse) is the highest domestic 50-over cricket competition in the Netherlands.
Until 2016 the league featured 8 teams playing in a double round-robin format, followed by relegation and championship play-offs.
From 2017 the league reverted to a simple ten-team double round-robin format.
Based in The Hague the club was formed in 1878 and won the first Dutch title in 1884.
The club was so dominant in Dutch cricket in the years after World War I that its Second XI was allowed to play in the top division and won the title five times between 1928 and 1935 - as well as sharing the title with the HCC First XI in 1926.
