The Tykes were officially relegated last month when their fate was confirmed at Yorkshire rivals Huddersfield Town.
With Poya Asbaghi leaving his role as head coach, important decisions need to be made this summer as the Reds look to secure an immediate return to the second tier.
Barnsley can take heart from their South Yorkshire neighbours Sheffield Wednesday and Rotherham United, who were both relegated last campaign.
The Millers will be back in the Championship next term while the Owls are in the League One play-offs as they aim to get back in the second tier at the first time of asking.
As well as planning for this summer, Barnsley have a host of players entering the final year of their contracts, as well as a handful whose deals expire at the end of this season.
Here we run through the contract situation of every Tykes player whose deal is set to run out in the summer of 2023 or sooner.
