2023–24 Forest Green Rovers F.C. season

The 2023–24 season is the 135th season in the history of Forest Green Rovers and their first season back in League Two since the 2021–22 season following their relegation from League One in the previous season. The club are participating in League Two, the FA Cup, the EFL Cup, and the 2023–24 EFL Trophy.

Pre-season and friendlies
On 7 June, FGR announced four pre-season fixtures, against Melksham Town, Coventry City, Everton Under-21s and Plymouth Argyle. A fifth was later added, against West Bromwich Albion.

Matches
On 22 June, 2023 the EFL League Two fixtures were released.

FA Cup
Forest Green Rovers were drawn away to Scarborough Athletic in the first round. This match was played three times before a winner was confirmed by the Football Association, due to Forest Green Rovers fielding an ineligible player, under rule 109 of the FA Cup competition rules, in the original tie which ended in a 1-1 Draw. The player was on loan with Forest Green Rovers, but they had not received permission from the parent club to play him in the FA Cup. The FA ordered the match to be replayed on 6 December. This caused a knock-on effect of the second round tie against Blackpool being postponed until the original first round match had been replayed. The match against Blackpool was originally scheduled for 2 December 2023, and subsequently played on 19 December 2023

EFL Cup
FGR were drawn at home to Portsmouth in the first round.

EFL Trophy
In the group stage, Forest Green were drawn into Southern Group A along with Walsall, Shrewsbury Town and Brighton & Hove Albion U21. After topping the group, Forest Green Rovers were drawn at home to Oxford United.
