The Czech National Football League is the second level professional association football league in the Czech Republic. Before 2013 it was known as 2. liga or Druhá liga. The top two teams each season are eligible for promotion to the Czech First League. The league replaced the I.ČNL (I. Česká národní liga; First Czech National League), which had been established following the end of the nationwide Czechoslovak Second League in 1977. The league became known as simply II. liga (Second League) in 1993 following the establishment of the Czech Republic as an independent state.
