NL, is the third tier of the Croatian football league system.

In its inaugural season, the league had four divisions (North, Center, South and West).

[citation needed] As of 2018, teams are promoted only if they have a valid license to the 2.HNL.

For example, NK Vinogradar won the 2017, 2018 and 2019 west division, but were denied promotion since they did not apply for a license.

[6] From the season 2022–23 onward, it is a unified league just as the top two tiers.
