NK Dinamo Zagreb Academy (also known as Hitrec-Kacian) are the youth team of Dinamo Zagreb. The academy was founded on 27 December 1967. There are a total of ten age categories within the academy, the oldest being the Junior Team (under-19) and youngest being the Zagići II Team (under-8).
The first junior team was formed in 1945 and the coach was the famous Građanski Zagreb goalkeeper Maks Mihelčić. Soon after that, Márton Bukovi joined the youth squad as an expert coach, but left after two years following his disappointment with the disbanding of Građanski. The junior team won a treble in 1950 (Zagreb's, Croatian and Yugoslav championships) under the leadership of Mirko Kokotović.
In 1952 Branko Horvatek started training one of the best junior generations the club ever had. Some of the famous players that played in that generation were Dražan Jerković, Mladen Košćak, Marijan Kolonić and Mladen Klobučar. The decision to form the youth academy Hitrec-Kacian was brought on 27 December 1967 with Horvatek being elected as its first director. Apart from him, many other famous Croatian coaches worked with the generation that was very successful in the period of 1972-1974 in Yugoslav junior competitions. Some of them include: Zorislav Srebrić, Marko Jurić, Pero Dujmović, Vladimir Čonč, Ivan Đalma Marković, Mirko Belić, Rudolf Cvek and Zdenko Kobešćak.
