The 2017 EFL League Two play-off final was an association football match played on 28 May 2017 at Wembley Stadium, London, between Blackpool and Exeter City. The match determined the fourth and final team to gain promotion from EFL League Two, English football's fourth tier, to EFL League One. The top three teams of the 2016–17 EFL League Two season gained automatic promotion to League One, while the teams placed from fourth to seventh in the table took part in play-off semi-finals; the winners of these semi-finals competed for the final place for the 2017–18 season in League One. Blackpool finished in seventh place while Exeter ended the season in fifth position. Luton Town and Carlisle United were the losing semi-finalists.

The match kicked off around 3 p.m in front of 23,380 spectators and was refereed by Darren England. Three minutes into the game, Potts put Blackpool ahead: Jack Payne made a long pass to Mark Cullen, who played it to Potts. He ran on and struck the ball first-time into the far corner of the Exeter goal. With five minutes of the half remaining, David Wheeler scored the equaliser with a lob over Sam Slocombe from just inside the Blackpool penalty area to make it 1–1 at half-time. In the 64th minute, Cullen put Blackpool back into the lead. Potts made a run into the Exeter penalty area and crossed the ball: Pym deflected it with his foot only for Cullen to finish it with an outstretched leg. Late pressure from Exeter failed to produce any goals, and despite five minutes of injury time, the match ended 2–1 to Blackpool who were promoted to League One.

Blackpool finished their following season in twelfth place in League One. In their next season, Exeter City finished in fourth position in League Two and qualified for the play-offs where they lost 3–1 against Coventry City in the final.

Exeter City finished the regular 2016–17 season in fifth place in EFL League Two, the fourth tier of the English football league system, two places ahead of Blackpool. Both therefore missed out on the three automatic places for promotion to EFL League One and instead took part in the play-offs to determine the fourth promoted team. Exeter City finished fourteen points behind Doncaster Rovers (who were promoted in third place), and sixteen behind Plymouth Argyle (promoted in second) and league winners Portsmouth. Blackpool ended the season two places and one point behind Exeter City.

Blackpool's opponents for their play-off semi-final were Luton Town with the first match of the two-legged tie being held at Bloomfield Road in Blackpool on 14 May 2017. Mark Cullen put the home side ahead after 19 minutes with a low shot but Luton replied, first through Dan Potts and then Isaac Vassell, to make it 2–1 at half-time. Two minutes into the second half, Cullen levelled the game with his second goal, a strike from around 25 yards (23 m). He completed his hat-trick midway through the half with a penalty and the match ended 3–2 to Blackpool. The second leg of the semi-final took place at Kenilworth Road in Luton four days later. Nathan Delfouneso opened the scoring for the visitors midway through the first half before Kelvin Mellor's own goal made it 1–1. Scott Cuthbert's header just before half-time made it 2–1 to Luton and twelve minutes after the break, Danny Hylton converted a penalty to increase his side's lead. Armand Gnanduillet's header made it 3–2 with less than 15 minutes remaining, and in the fifth minute of injury time, an own goal from Stuart Moore ensured the match ended 3–3. With an aggregate victory of 6–5, Blackpool progressed to the final.

Exeter City faced Carlisle United in their play-off semi-final, the first leg being played at Brunton Park in Carlisle on 14 May 2017. The visitors took the lead on 15 minutes when Joel Grant scored but Exeter's Jordan Moore-Taylor scored an own goal to level the match. Ryan Harley restored Exeter's lead just before half-time and David Wheeler made it 3–1 eleven minutes into the second half. John O'Sullivan's cross floated into the Exeter goal to make it 3–2 midway through the second half and Shaun Miller's header levelled the match which ended 3–3. The second leg of the semi-final was played St James Park in Exeter four days later. Ollie Watkins scored the only goal of the first half to put Exeter ahead on aggregate. With eleven minutes of the game remaining, Watkins scored his and Exeter's second, but Jason Kennedy pulled one back for the visitors two minutes later. O'Sullivan scored in the 90th minute to make it 2–2, but five minutes into injury time, Jack Stacey scored for Exeter to make it 3–2, and Exeter won the tie 6–5 on aggregate.

Blackpool had been relegated to League Two the previous season and were thus aiming for an instant return to League One. Exeter City had played in League Two since being relegated at the end of the 2011–12 season. During the regular season, Blackpool were undefeated in the two matches between the clubs, winning 2–0 at Bloomfield Road in August 2016 and drawing 2–2 at St James Park the following February. Blackpool's top scorers during the regular season were Potts with 12 (10 in the league, 1 in the FA Cup and 1 in the League Cup) followed by Vassell with 11 (all in the league). Exeter's leading marksmen were Wheeler who had 17 goals for the season (all in the league), followed by Reid with 14 (13 in the league, 1 in the FA Cup) and Watkins with 13 (all in the league).

Exeter City were allocated 20,000 tickets for the match. Blackpool supporters were allocated the east end of Wembley Stadium while Exeter City fans occupied the west end. Due to an ongoing dispute with Blackpool owner, Owen Oyston and his family, Blackpool Supporters' Trust called on the club to donate its share of its gate receipts to charity so they could attend the match without their money going towards the Oyston family.
