2016–17 UEFA Europa League knockout phase

The 2016–17 UEFA Europa League knockout phase began on 16 February and ended on 24 May 2017 with the final at Friends Arena in Solna, Sweden, to decide the champions of the 2016–17 UEFA Europa League. A total of 32 teams competed in the knockout phase.

Times up to 25 March 2017 (round of 32 and round of 16) were CET (UTC+1), thereafter (quarter-finals and beyond) times were CEST (UTC+2).

Round and draw dates
The schedule of the competition was as follows (all draws were held at the UEFA headquarters in Nyon, Switzerland, unless stated otherwise).

Matches could also be played on Tuesdays or Wednesdays instead of the regular Thursdays due to scheduling conflicts.

Format
The knockout phase involved 32 teams: the 24 teams which qualified as winners and runners-up of each of the twelve groups in the group stage, and the eight third-placed teams from the Champions League group stage.

Each tie in the knockout phase, apart from the final, was played over two legs, with each team playing one leg at home. The team that scored more goals on aggregate over the two legs advanced to the next round. If the aggregate score was level, the away goals rule was applied, i.e. the team that scored more goals away from home over the two legs advanced. If away goals were also equal, then thirty minutes of extra time was played. The away goals rule was again applied after extra time, i.e. if there were goals scored during extra time and the aggregate score was still level, the visiting team advanced by virtue of more away goals scored. If no goals were scored during extra time, the tie was decided by penalty shoot-out. In the final, which was played as a single match, if scores were level at the end of normal time, extra time was played, followed by penalty shoot-out if scores remained tied.

The mechanism of the draws for each round was as follows:
 * In the draw for the round of 32, the twelve group winners and the four third-placed teams from the Champions League group stage with the better group records were seeded, and the twelve group runners-up and the other four third-placed teams from the Champions League group stage were unseeded. The seeded teams were drawn against the unseeded teams, with the seeded teams hosting the second leg. Teams from the same group or the same association could not be drawn against each other.
 * In the draws for the round of 16 onwards, there were no seedings, and teams from the same group or the same association could be drawn against each other.

On 17 July 2014, the UEFA emergency panel ruled that Ukrainian and Russian clubs would not be drawn against each other "until further notice" due to the political unrest between the countries.

Round of 32
The draw was held on 12 December 2016. The first legs were played on 16 February, and the second legs were played on 22 and 23 February 2017.
