2017 Tercera División play-offs


The 2017 Tercera División play-offs to Segunda División B from Tercera División were the final playoffs for the promotion from 2016–17 Tercera División to 2017–18 Segunda División B. The first four teams in each group took part in the play-off.

Format

The eighteen group winners have the opportunity to be promoted directly to Segunda División B. The eighteen group winners were drawn into a two-legged series where the nine winners will promote to Segunda División B. The nine losing clubs will enter the play-off round for the last nine promotion spots.
The eighteen runners-up were drawn against one of the eighteen fourth-placed clubs outside their group and the eighteen third-placed clubs were drawn against one another in a two-legged series. The twenty-seven winners will advance with the nine losing clubs from the champions' series to determine the eighteen teams that will enter the last two-legged series for the last nine promotion spots. In all the playoff series, the lower-ranked club play at home first. Whenever there is a tie in position, a draw determines the club to play at home first.
