2017–18 Liga Națională (men's handball)

The 2017–18 Liga Națională was the 60th season of Romanian Handball League, the top-level men's professional handball league. The league comprises 14 teams. Dinamo București were the defending champions, for the second season in a row.

Promoted from Divizia A
 * Politehnica Iași

From Liga Națională
Relegated to Divizia A
 * CSM Satu Mare
 * Adrian Petrea Reșița

Relegation play-offs
The 11th and 12th-placed teams of the Liga Națională faced the 2nd and 3rd-placed teams of the Divizia A, from both Seria A and Seria B. The first place from each play-off group promoted to Liga Națională.

Third place
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.

Notes:
 * HC Buzău qualified for 2018–19 Liga Națională and Atletico Alexandria qualified for 2018–19 Divizia A.
