The 2017–18 ABA League First Division was the 17th season of the ABA League with 12 teams from Serbia, Croatia, Slovenia, Montenegro, Bosnia and Herzegovina and the Republic of Macedonia participating in it. It was the inaugural season as the first tier as a part of two level competition.

Format changes
On May 23, 2017, ABA League Assembly has decided that there will be 12 clubs competing in the league in the 2017–18 season. Having analysed the current situation in European and the regional basketball, as well as the fact that the ABA League is still not officially recognized by the national basketball federations, and with a goal to protect the interests of the ABA League founding clubs, the clubs that have competed in the 2016–17 season will have a right to participate in the forthcoming season as well and the priority of participation will be given to the founders of the ABA League (from the 2015–16 season). The formula to determine the participants which will be respected is the following:


 * 🇷🇸 – three clubs
 * – three clubs
 * – one club
 * 🇧🇦 – one club
 * 🇲🇪 – one club
 * 🇲🇰 Macedonia – one club

Two additional spots will be allocated to the clubs from countries, whose clubs have achieved the best coefficients in the country rankings during the 2016–17 season. Those two countries are Serbia and Montenegro. The places from Serbia will be filled in accordance with the final standings of the Basketball League of Serbia, in accordance with the recognition and cooperation with the ABA League.

In accordance with the previously mentioned decisions, the participating clubs of the ABA League for the 2017–18 season are: Cedevita, Zadar, Cibona, Union Olimpija, Igokea, Budućnost VOLI, MZT Skopje Aerodrom and Mornar, while the remaining four places (from Serbia), were determined in accordance with the standings in the Basketball League of Serbia.

National standings

By using this coefficient majority of places for current season are allocated, while the remaining places are given via wild cards from league board.
