The 2017–18 Total League season was the 65th season of the first division of the professional basketball in Luxembourg.
Amicale defended successfully its title and achieved their eighth league.
The regular season consisted in a double-legged round robin tournament where the six first qualified teams advanced to the group for the title, while the other four teams played for avoiding relegation.
In the second stage, all wins from the regular season counted for the standings, while the points are reset. The four first qualified teams in the group for the title, advanced to the playoffs, played in a format of best-of-three-games series.
Teams of the relegation group play twice against themselves and twice against the four first qualified teams of the first stage of the Nationale 2. The two worst teams would be relegated.
