할주 JK 라아그리

Harju Jalgpallikool was founded on 27 August 2009 with the aim of focusing on youth football and developing players for the Estonian national youth teams and foreign academies. Harju JK entered senior football in 2015, when their first team entered IV Liiga, the lowest level of football in Estonia.

In 2019, Harju JK appointed Portuguese Victor da Silva as their manager and in the following seasons gained promotion four years in a row. During the period, Harju's team consisted mostly of their youth system players, which resulted in youth prospects Karel Mustmaa signing a three-year professional contract with Benfica and Imre Kartau moving to Venezia F.C. Harju JK won Esiliiga in the 2022 season and were promoted to Estonian top flight league Premium Liiga for the first time in its history. Despite a number of strong performances, the club finished the 2023 season in last place with 23 points and were relegated back to Esiliiga.
