The 2016–17 Segunda División play-offs took place in June 2017 and determined third team which was promoted to the top division.
Getafe achieved the promotion berth one year after their relegation.
The team that scored more goals on aggregate over the two legs advanced to the next round.
If away goals were also equal, then thirty minutes of extra time would be played.
If no goals were scored during extra time, the winner would be the best positioned team in the regular season.
