Due to the merger, Red Star changed its name to Red Star Olympique and dropped its navy blue and white combination for a simple white blouse. In 1928, Red Star won its fourth Coupe de France title of the decade defeating CA Paris 3–1 at the Stade Olympique Yves-du-Manoir in Colombes. In July 1930, the National Council of the French Football Federation voted 128–20 in support of professionalism in French football. Red Star were among the first clubs to adopt the new statute and, subsequently, became professional and were founding members of the new league. In the league's inaugural season, Red Star were relegated after finishing in the bottom three of its group. As a result, the club played the following season in the inaugural season of the Division 2. Red Star won the league and returned to the first division for the 1934–35 season. Following the club's return to Division 1, Red Star switched its colours from white to the green and white that exists today. In 1967, they merged with Toulouse FC (not the current club) out of the latter club's financial reasons and bought Toulouse's place in the top division. The merged club last played in first division in the 1974–75 season. After a long spell in the lower leagues, following a successful 2014–15 campaign, the team won promotion to Ligue 2, the second tier of French football. In their first season back in Ligue 2, Red Star finished 5th on the table missing promotion to Ligue 1 by a single point. In the 2016–17 Ligue 2 season, Red Star finished 19th and were relegated back to the third division of French football. Due to safety regulation issues with Stade Bauer, Red Star has been forced to play at different stadiums the past few seasons when in Ligue 2. They have employed Stade Jean-Bouin in the past and then used Stade Pierre Brisson located in Beauvais. Since returning to the third tier in 2019, the club has returned to playing home matches at Stade Bauer. In 2018, Red Star were promoted back to Ligue 2 as champions of the Championnat National. They were relegated again the following season, finishing bottom of Ligue 2. Their relegation was confirmed on 27 April 2019 after losing 2–1 to champions FC Metz.
