The Posh are looking to become two-time winners of the competitions, while the Chairboys are hoping to get their hands on the trophy for the first time in their history.
Match preview
Peterborough are set to make their first appearance in the EFL Trophy final since they beat Chesterfield 2-1 to clinch the silverware in 2013-14.
Darren Ferguson, who was in charge ten years ago, now has the opportunity to lead the club to their second EFL Trophy after overseeing knockout round wins over Arsenal Under-21s, Crawley Town, AFC Wimbledon and Blackpool.
The Peterborough boss is also hoping to guide his team to the Championship, with the Posh currently sitting in fourth position in the League One table.
They bounced back from consecutive defeats to record a narrow 2-1 win in Monday's away game against Leyton Orient thanks to goals from Hector Kyprianou and Ephron Mason-Clark.
The Posh may have won seven of their last nine competitive matches, but they have struggled in recent meetings with Wycombe, having failed to win any of their previous five head-to-head matches since running out 4-0 winners in January 2020.
While Peterborough are likely to be involved in the playoffs, Wycombe's league campaign is set to peter out to a comfortable midtable finish.
The Chairboys played out a goalless draw in Monday's away clash with Blackpool to leave them in 13th position with 51 points to their name after 40 matches.
Although there may be little to play for in the league, Wycombe still have the chance to make the 2023-24 campaign a memorable one after reaching their first EFL Trophy final.
After progressing from the group stage, Matt Bloomfield's side saw off the Under-21 teams of Fulham, West Ham United and Brighton & Hove Albion, before they beat Bradford 1-0 in the semi-final following Matt Butcher's 91st-minute winner.
Wycombe are now preparing to face a League One side for the first time in the competition, and they will be hoping the encounter will be as successful as February's meeting with Peterborough at Adams Park, where they produced a free-scoring display to claim a 5-2 victory.
