from 1934 to 2017. The club was founded on 16 May 1926 from a merger between local teams
Clubul Sportiv and
Societatea Sportivă Muncitorească, the new team was named
SS UDR (
Sociatatea Sportivă a Angajaților Uzinelor de Fier și Domeniile din Reșița – "Sports Society of Employees of the Factories and Domains from Reșița"), the first coach of the team being native Ernest Loukota who also helped at the merger, the main starting 11 in the club's first year of activity being:
Ștefan Czinczer – Szilágyi, Rech – Bundy, Andresz, Pecsenovszky – Grosz, Pázler, Lakatos,
Adalbert Deșu, Keller. In the
1930–31 season, UDR won the Romanian West League and qualified to the national finals, where it defeated with 2–0
Societatea Gimnastică Sibiu in the final after a double scored by
Eugen Lakatos, coach Loukota using the following 11: Carol Damacsek – Alexandru Pomacsek, Györi – Sinko, Sepi, Jozsef Bundi – Fibișanu,
Eugen Lakatos,
Silviu Ploeșteanu, Jozsef Kilianovics, Moise. In the
following season, the club reached again the championship final, losing it with 3–0 in front of
Venus București, this time coach Loukota used the following players: Carol Damacsek –
Iosif Czako, Györi – Sinko, Sepi – Jozsef Bundi, Kilianovics – Tudor,
Silviu Ploeșteanu,
Eugen Lakatos, Moise, Keller. After
World War II and the advent of the
Communist regime, professional football was forbidden, UDR merged with a local labor union team,
Locomotiva and was renamed Oțelul (Steel) Reșița and after several further name changes, it was ultimately branded Metalul Reșița. During its 87-year history, the club won one championship and one cup and has played for 16 seasons in
Liga I, the last time in the
1999–2000 season. The early 2000s brought financial problems to the Domanului Valley team and, in 2004, Reșița was dissolved and converted to
FC Universitatea Craiova's reserve team. In 2005, the club was refounded as
FCM Reșița and bought its place in the second tier from
Tricotaje Ineu, but lost its brand, record and the right to use the name of CSM Reșița. The club was dissolved in the autumn of 2008 due to financial difficulties. In the summer of 2009, it was brought back to life, this time with the name of
Școlar Reșița, playing in
Liga III, Romania's third league. In the summer of 2012, it was renamed again, this time returning to the old name of
FCM Reșița. In the
2012–13 season, the club finished third in Liga III. The objective for the 2013–14 season was initially to be promoted to
Liga II after a six-year absence, but in the summer of 2013
Damila Măciuca was moved to Reșița and was renamed to
Metalul Reșița. The municipal government of
Reșița chose to support this new team, forcing Școlar Reșița to enter
Liga IV due to the loss of funding. In 2015, relations between Metalul and the Municipality of Reșița cooled and the latter resumed its financial support for CSM Școlar. Metalul moved to Snagov in 2016 and was renamed a year later to
Sportul Snagov. On the other hand, CSM Școlar was promoted back to Liga III at the end of the
2015–16 season, winning the
Liga IV Caraș-Severin and the promotion play-off 6–1 away in the first leg and by forfeit in the second leg against Pandurii Cerneți,
Mehedinți County winners. The squad, led by
Dan Potocianu in the first half of the season and by
Leontin Doană after the winter break, included, among others, Petruț, Domăneanț,
Szijj, Banac, Covăsală, Coviț, Negrei, Costescu, Al. Ciucur, Breșneni, Bloju, Costachi, Liuba, V. Marcu, C. Doană, Țoțu, Beloescu, and Curelea. In
Liga III, Școlar Reșița competed under Leontin Doană and finished runners-up in Series IV in the
2016–17 season, just one point behind leaders
Ripensia Timișoara. In the
2017–18 season,
Roco Sandu was appointed as the new head coach. However, poor results led to his replacement by
Daniel Oprița, who guided the team to another runners-up finish in Series IV, this time behind
Șirineasa, and also led them to the Round of 32 of the
Cupa României, where they faced
Viitorul Constanța and lost 2–4. In the
2018–19 season, Octavian Benga took charge of CSM Școlar Reșița, but after poor results that saw the Valea Domanului side drop from promotion contenders in Series IV closer to the relegation zone, he resigned after nine rounds and was replaced by
Leontin Doană. Doană led the team to overcome the eight-point gap from before the winter break behind first-placed
Șoimii Lipova, ultimately finishing two points ahead and securing promotion to the second tier after an eleven-year absence. The club also regained its traditional logo and name, being renamed CSM Reșița in the summer of 2019. In the following campaign, Reșița reached the Round of 32 of the
Cupa României, where it was eliminated by
Universitatea Craiova after a 0–1 loss at
Ion Oblemenco Stadium, with a lineup that included
Zimmermann, L. Acka,
Ehmann, Vasiu (Vlădia 67′), Banac, Săulescu,
Danci,
Cristea (Poiană 55′),
Vădrariu,
Dat (
Cioablă 58′), and D. Ene. In the
2019–20 Liga II season, with the team in the relegation zone after sixteen rounds, Reșița parted ways with Leontin Doană, who was replaced by former Romanian international
Dorinel Munteanu. Munteanu led the team to 15th place before the league was interrupted in March 2020 due to the COVID-19 pandemic. Munteanu left Reșița during the summer of 2020, and
Alexandru Pelici took charge for the
2020–21 campaign, but resigned after eight rounds due to poor results. He was replaced by
Alin Minteuan, who in turn stepped down before the final round of the regular season, in which the team finished in 17th place. Subsequently,
Adrian Falub was appointed as head coach, and after placing second from bottom in Group B of the play-out stage, Reșița returned to the third tier after two seasons in
Liga II. After relegation, Reșița appointed former Romanian international
Dan Alexa as head coach for the
2021–22 Liga III campaign, aiming for a quick return to the second tier. The team won Series VII, finishing ten points clear at the end of the regular season and extending the gap to twenty points after the series play-off stage ahead of 2nd-placed
Deva. Reșița qualified for the promotion play-offs, where it eliminated
Ghiroda in the first round (1–0 away and 1–1 at home). In the decisive tie for promotion, however, the team was eliminated by
Dumbrăvița, losing 2–4 on penalties after a 0–0 away draw and a 1–1 result at home, ending a season in which they went unbeaten in regular time. Alexa did not continue as head coach and was replaced by Călin Cheregi. Under Cheregi, the Rossoneri reached the play-off round of the
Cupa României but were eliminated after a 0–4 defeat to
Mioveni. During the
2022–23 Liga III season, they went on to win Series VIII and qualified for the promotion play-offs, where they eliminated
Filiași in the first round (2–2 away and 5–0 at home). In the decisive tie for promotion, Reșița defeated
Deva with two 3–2 victories, securing promotion to the second tier after two years. In the
2023–24 campaign, Reșița had a poor start to the season, losing both of their opening
Liga II matches, and was also unexpectedly eliminated in the third round of the
Cupa României after a 0–1 defeat to third-tier side Phoenix Buziaș, after which Călin Cheregi resigned. Flavius Stoican was subsequently appointed as head coach and led the team to 10th place in the regular season and first place in Group A of the play-out stage. Reșița had a strong
2024–25 campaign, finishing 5th in the regular season and advancing to the promotion play-off stage, where it eventually finished 6th. The team also reached the group stage of the
Cupa României, won Group D, and advanced to the quarter-finals for the first time in twenty-five years, where it was defeated 0–4 by
Hermannstadt. The squad included, among others, Dincă, Goga,
Élton,
Dudea,
Erico, Dolghi,
Bocșan, Chera, Salhi,
Tucaliuc,
Cioiu, Gașpăr, Negru,
Jerdea, Doană, Lascu, Samaké,
Florescu, Fărăgău, and R. Burlacu. In the
2025–26 season, the Red and Blacks were eliminated in the third round of the
Cupa României after a 0–1 defeat to Liga III side
Știința Poli Timișoara. Flavius Stoican left Reșița after nearly three years in charge following a 1–3 home defeat to
Corvinul Hunedoara and the failure to secure a place in the top-six promotion play-off. Stoican was replaced by former Reșița player and club legend
Leontin Doană. ==Ground==
