The 2017–18 Divizia A was the 60th season of the Romanian men's handball second league.
At the end of the season the first place from both series promoted to Liga Națională, the 2nd and 3rd places from both series played a promotion play-off together with 11th and 12th place from Liga Națională.
The first place from each play-off group promoted to Liga Națională.
Because the winner of Divizia A, Seria B, CSM Oradea declined the participation in the 2018–19 Liga Națională, another play-off match was organised to establish the third place and implicitly the last team promoted.
The match was played between the 2nd places from the two Relegation play-offs series.
