Fudbalski klub Mačva Šabac (Serbian Cyrillic: Фудбалски клуб Мачва Шабац, lit.

In the period between the two world wars Mačva developed a fierce rivalry for the titles in those leagues with FK Vojvodina.

By early spring of 1928, Mačva finished at the top of the First League of the Novi Sad District where they defeated their main rivals Vojvodina.

Then, the draw determined that the final match would be played in Šabac against ZAŠK from Zemun, which Mačva smashed by 6:1 with goals by Bora Kesić, Milan Perić, Raduška Gajić and Kokan Stevanović.

[6][7] After becoming Belgrade Subassociation Provincial League champions, Mačva became notorious and the main daily newspaper Politika consistently used the nickname Provincial Uruguay, especially after their surprising win against SK Jedinstvo Beograd by 3:2 in Belgrade, and after their successful tour in Greece where they beat Thessaloniki sides Iraklis by 3:1, and Aris by 4:2.

They played well against BSK Belgrade and Hajduk Split and won in competition with the three-time Yugoslav champions Građanski Zagreb.

Under the club presidency of former Yugoslavia goalkeeper Ivica Kralj, FK Mačva returned to top flight football, after a six decade absence.
