The name Rovers was adopted in 1893, and the following year the club were founder member of the Mid-Gloucestershire League. but left the league at the end of the 1922–23 season to return to the Stroud and District League. Forest Green finished as runners-up in 1924–25 and 1925–26, Although the club finished as runners-up in 1952–53, they were relegated to Division Two at the end of the 1954–55 season. However, they were Division Two champions the following season, and were promoted back to Division One.
Regional leagues Forest Green's
first season in the Hellenic League Premier Division saw them finish fourth. Although they then spent two seasons in lower mid-table, a third-place finish in
1978–79 was the start of a successful four years, culminating in the
1981–82 season, in which they won the Hellenic League and reached the final of the
FA Vase.
Another season in mid-table was followed by two in which they finished in the bottom five. However, they lost 1–0 to
Kingstonian. The
following season saw another first as the club reached the first round of the
FA Cup for the first time; after beating
Guiseley 6–0 in the first round, they lost 3–0 at home to
Torquay United in the second. In
2007–08 the club defeated Football League opposition in the FA Cup for the first time, beating
Rotherham United 3–0 in a first round replay, before losing 3–2 at
Swindon Town. The
following season saw them reach the third round of the Cup for the first time, beating
Team Bath and then
Rochdale to set a third round tie at home to
Derby County which they lost 4–3 in front of a record crowd of 4,836. The club was then taken over by
Ecotricity founder
Dale Vince; Vince set out plans to make the club more eco-friendly, including removing red meat from players' diets, stopping selling meat products in the ground and treating the pitch with organic fertiliser. Forest Green finished fifth in the Conference in
2014–15, qualifying for the promotion play-offs; they went on to lose 3–0 on aggregate to
Bristol Rovers in the semi-finals. The
following season saw them finish as runners-up in the renamed National League, their highest-ever league position; in the subsequent play-offs they defeated
Dover Athletic 2–1 in the semi-finals, before losing 3–1 to
Grimsby Town in the final at
Wembley. In the
2020–21 season, the club sacked their then manager
Mark Cooper after they had failed to secure a win in six matches; losing four consecutively.
Jimmy Ball stepped in to lead the team until the end of the season. They finished sixth within the league, leading to another play-off campaign. This campaign saw them lose 5–4 on aggregate to
Newport County.
League Two title and promotion (2021–22) Following the 2020–21 campaign, the club hired
Rob Edwards as their head coach in June of 2021, leaving his role as England U16 Head Coach and U20 Assistant for the FA. He was joined by Richie Kyle as assistant coach. The club began the 2021–22 season with a strong start; winning seven of their opening ten league matches. This placed them top of the league, a position they would hold until round 42 of the competition. At one point, they were 14 points ahead of the team in second position. However following game week 42, Forest Green were caught and overtaken by
Exeter City, who had climbed up the table after a club-record 11 successive home league wins between October and April. With just four games remaining, Exeter City were on 80 points, and Forest Green on 79. This resulted in Forest Green falling a point behind Exeter City, meaning that going into the final game, an Exeter City victory against
Port Vale would win the league no matter the score in the Forest Green game against
Mansfield Town. However, the opportunity to win the league on the final day was still present for Forest Green; provided Exeter City drew or lost, and Forest Green won or drew their match against Mansfield. In the Exeter City game, Port Vale were leading 1–0 following a goal from
James Wilson. As things stood going into the second halves, Exeter were winning the league by one point, although a draw or win for Forest Green would win the league (assuming the result in the Exeter game remained the same). As the games progressed, Ebou Adams scored in the 64th minute in the Forest Green game to make it 1–1. Mansfield then restored their lead with a goal from
Jordan Bowery in the 78th minute, making it 2–1 to the home side. Just two minutes later, Forest Green equalised again with a goal from
Josh March. All the while, it was still 1–0 in the Exeter City game, As both games progressed to their end, neither result changed, crowning Forest Green as the League Two champions for the first and only time in their history, and also the first time they had ever been promoted to League One. Manager Rob Edwards said after the game that it was "surreal" and "incredible" to finish top of the league. In the
2022 PFA League Two Team of the Year, Forest Green had five players included, with Wilson, Cadden, and Stevens named again alongside
Ebou Adams and
Jamille Matt.
Consecutive Relegations (2022–2024) After their success in 2021–22, manager Rob Edwards announced he was leaving the club and joining
Watford. At the time, the chairmen Vince was publicly unhappy, saying that negotiations between Edwards and Watford took place "behind our backs." He also said that "It takes a bit of the shine off winning promotion. If there's any karma in football they'll languish in the Championship and we'll meet them there in a few years' time." To replace Edwards,
Ian Burchnall was hired as head coach to lead the team into the
2022–23 season. Having won just five of their opening twenty-eight league matches in the 2022–23 season, Burchnall was sacked as head coach and replaced by
Duncan Ferguson. Despite this appointment, Rovers were relegated back to League Two after finishing in 24th position. Dingley was soon replaced by
David Horseman, who led the team at the start of the 2023–24 season. He was sacked in December 2023, and replaced by
Troy Deeney, who at the time was a player at the club. Deeney was also sacked just 29 days following his appointment after publicly criticising his players and not winning a match during his six game tenure. He was replaced by
Steve Cotterill. At the end of the season, Rovers finished in the relegation zone again in League Two after finishing 24th, thus suffering the indignity of back-to-back relegations into the National League, ending their seven-year spell in the Football League. Cotterill left the club on 24 June 2025. On 1 July 2025,
Robbie Savage was appointed first team manager, joining from
Macclesfield. In the
2025–26 season, Forest Green finished in seventh position with 81 points, earning them a play-off quarter-final match away against
Boreham Wood. Forest Green lost 1–0 after
extra time. ==Green credentials==
