In 1901, Joan Saus and a group of youngsters from the Sabadell Catalan Centre founded Centre d'Esports Sabadell, which became fully legalized on 5 June 1906. The club's first games were held in a grass field at Prat de Sant Oleguer but, on 3 June of that year, a stadium in the Creu Alta District was inaugurated, in a game against "Team X" from Barcelona, later known as RCD Espanyol; in 1912, in the same site, the first game under floodlights was played in the country.

In 1933–34, the club won its first major trophy, the Catalan Football Championship, which allowed the winner to participate in the Copa del Presidente de la República. During the former tournament, it won 15 games and drew once, reaching the latter's final in the following season, losing 0–3 to Sevilla FC at the Chamartín Stadium.

Sabadell first competed in La Liga in the 1943–44 season, finishing ninth. It improved to fifth in 1946–47, ranking in front of Real Madrid and only four points behind champions Valencia CF, just one season after returning from Segunda División.

In 1968–69, Sabadell, guided by manager Pasieguito, finished a best-ever fourth as the top flight already consisted of 16 clubs. Subsequently, it competed in the Inter-Cities Fairs Cup, losing to Club Brugge K.V. of Belgium in the first round (3–5 on aggregate); in 1972, a seven-year ran in the top division came to an end, as the Arlequinats were relegated after finishing dead last.

CE Sabadell became a public limited sports company in 1991, being relegated to Segunda División B two years later, and immediately to Tercera División following severe economic problems. The club spent the following seventeen years in the third level (with the exception of 2006–07 in the fourth).

In the 2010–11 season, Sabadell, managed by Lluís Carreras, won its group in the regular season. In the playoffs, the team drew both games against SD Eibar, but was eventually promoted on the away goals rule following the 1–1 score at the Ipurua Municipal Stadium, returning to the professional divisions after 18 years.

Sabadell struggled in their return to the second level finishing in 19th place, being the first side in the relegation zone. However, they were spared when Villarreal CF dropped down a division in the top flight, which led to the automatic relegation of its reserve team Villarreal CF B. Sabadell finished second level as 16th in 2012–13 season, as 10th in the 2013–14 season. Finally Sabadell finished it as 21st and relegated to third level after 4 years.

Sabadell had a lot of financial problems after the relegation to Segunda B. Japanese owner Keisuke Sakamoto, who had bought the club in 2012, sold it to Aragón-based company Viacron in 2015. Esteve Calzada, a former member of FC Barcelona board and a marketing expert whose company worked for Manchester City, bought the club in 2017. Difficulties in finding a new investor meant that from 2017 to 2019 the club was more concerned with relegation avoidance than real hopes of promotion.

In August 2019, the club announced an historical agreement with a group of international investors (led by Pau Morilla-Giner), whereby this Group would both bail out the Club and achieve majority ownership through periodic capital infusions over the following three years to guarantee institutional stability and financial resources to achieve sustainable success. On the back of this, the Club secured promotion to the La Liga Smartbank Segunda División in July 2020 by beating Barcelona B 2–1 in the Segunda División B playoff final after five-years in third division.

The team was immediately relegated in the following 2020–21 season by the narrow margin of one single point, and joined the newly created 1a RFEF Division.

After three seasons in Primera Federación, the team was relegated to Segunda Federacion after failing to win the last game away against CD Lugo on 25 May 2024.

At the beginning of 2023-24 Season, Chairman Esteve Calzada resigned to become CEO of Saudi Club Al Hilal. Throughout this season, a new ownership group (led by venture capitalist Adam Rothstein and Club Chairman Pau Morilla-Giner) took control of the Club. In his first interview, Rothstein outlined the strategic plans for the years ahead.

At the end of 2024-25 Season, the team achieved promotion to Primera RFEF via a successful playoff run. During his end-of-season press conference, Club Chairman Pau Morila-Giner credited success to the following factors: committed players, stability, process-driven decision making and mental training.
