Lens in 2011 Hazard began his football career playing for hometown club
Royal Stade Brainois at age five. After spending five years at the club, Thorgan followed his brother Eden to
Tubize. At age 14, he was discovered by French club
Lens while playing for Tubize in a local tournament. Similar to his brother's move to Lille, his parents accepted an offer from Lens with the hope that the training facilities in France would be better, here he met fellow Belgium player and future
Chelsea teammate
Charly Musonda. Hazard's father later admitted Eden was much better than Thorgan, and that joining clubs in the
North of France was the best solution, stating, "They remained so close to home and, at the same time, they integrated at structures where they could grow, because in Belgium, unfortunately, it's a little empty for the training of youth." While in the club's youth academy, Hazard played for the Lens under-16 team, alongside players such as
Geoffrey Kondogbia and
Raphaël Varane, that won the 2008–09 edition of the
Championnat National des 16 ans 44. On 7 April 2010, Hazard signed his first professional contract after agreeing to a three-year deal until June 2013. Ahead of the
2010–11 season, Hazard trained with the senior team during the pre-season. On his pre-season debut, he scored a goal in a 1–1 draw with Belgian club
Roeselare. However, Hazard began the season with the club's
Championnat de France amateur team in the fourth division. He made his amateur debut on 8 August 2010, appearing as a substitute in a 2–0 victory over
Drancy. After spending most of the season playing concurrently with the reserve team in the CFA and with the under-19 team in the
Coupe Gambardella, on 9 May 2011, Hazard was named to the senior team for the first time on 11 May in a
Ligue 1 match against
Bordeaux. However, Hazard did not feature in the match and finished the 2010–11 campaign with no senior team appearances. Ahead of the
2011–12 season, Hazard was promoted to the senior team permanently and assigned the number 22 shirt. He made his professional debut in Lens' opening league match of the season against
Reims, appearing as a second-half substitute in a 2–0 defeat. He played 14 league games that season.
Chelsea On 24 July 2012, Chelsea confirmed on its website the club had agreed terms with Lens for the transfer of Hazard, shortly after they announced the signing of his brother Eden from Lille. He made his debut on 17 August 2012 in an Under-21 Premier League match, a 0–0 home draw against
Manchester City in what was to be his only appearance for Chelsea before leaving the club.
Zulte Waregem On 30 August 2012, Hazard was sent on a season-long loan move to
Belgian Pro League club

OH Leuven. Hazard scored his first goal on 31 October in a 4–1 home win against
Charleroi. On 16 May 2013, Hazard put in an impressive shift as he scored the game's opening goal from the penalty spot before providing two assists in a 5–2 defeat of
Club Brugge at the
Regenboogstadion in
Waregem. On 15 July 2013, Chelsea and Waregem agreed for Hazard to be loaned back for another year until the end of the 2013–14 season. Hazard scored a free-kick and assisted a goal as Zulte won their season opener against
Lierse on 27 July. On 2 August, the Belgian club announced Hazard would be replacing experienced defender
Davy De fauw as club captain, which was received with much anger from a section of the club's supporters. This led to Hazard handing the captain's armband back, less than 24 hours after receiving it. After the incident, it was rumoured the move to make Thorgan the club captain was one of the conditions in the loan deal imposed by Chelsea. On 28 November 2013, Hazard scored against
Wigan Athletic in a 2–1 win in the
UEFA Europa League group stage win away at the
DW Stadium. He was voted as Zulte's player of the season, and scored 17 goals in 53 matches across all competitions. Hazard also won the Belgian Player of the Year Award.
Borussia Mönchengladbach in 2015 On 5 July 2014, Hazard was loaned to
Borussia Mönchengladbach of the German

During an interview about his move becoming permanent in the summer, Hazard confirmed his deal does contain a buy-back clause and that he still dreams of returning to
Stamford Bridge in the future. In his interview, he said, "I am focusing on excelling at Borussia Monchengladbach, but I still hope to play for Chelsea one day." On 8 August 2015, in his first game after his transfer, Hazard scored in a 4–1 win at
FC St. Pauli in the first round of the
DFB-Pokal. Following the resignation of manager
Lucien Favre, who lost the first five matches of the Bundesliga, and
André Schubert's appointment, he was unable to find a place in the starting lineup. Hazard made his first start under Schubert on 20 December against
Darmstadt 98, eventually earning preference from Schubert over
Ibrahima Traoré on the right side. Hazard finished the season with four goals, two coming in a match against Hertha BSC on 3 April 2016 in a 5–0 win. Looking to improve his playing time and goalscoring heading into the year, Hazard scored his first ever hat-trick in a 6–1 victory over Swiss club
Young Boys in the second leg of the
UEFA Champions League play-off round on 24 August 2016. Mönchengladbach set a record with a 9–2 aggregate scoreline, the largest ever margin of victory in a play-off tie. On 17 September, Hazard and teammate
Raffael both scored first-half braces against
Werder Bremen in a Bundesliga match. With rumours that Chelsea were looking to exercise their buy-back clause on Hazard, and that the clause expired at the end of 2016, club sport director
Max Eberl claimed Chelsea did not actually have an explicit buy-back clause in Hazard's contract. Hazard, addressing these rumours, said, "I signed a contract here, because I want to play here." On 28 September, Hazard scored his first UEFA Champions League goal, opening the scoring against
Barcelona at
Borussia-Park before the visitors went on to win 1–2. On 25 November 2017, he scored from the penalty spot to help his side defeat the

Alassane Pléa and Raffael each scored hat-tricks in an 11–1 win at fifth-tier
BSC Hastedt in the first round of the cup.

Borussia Dortmund on a five-year contract for a reported fee of €25.5 million. He joined the club at the same time as new teammate
Julian Brandt, who arrived from
Bayer Leverkusen. He was part of the squad that won the
DFB-Pokal in the
2020–21 season.
Loan to PSV On 31 January 2023, Hazard joined
Eredivisie club
PSV on loan until the end of the season. He scored on his debut in a 2–2 draw against
Feyenoord. During his spell in Eindhoven, Hazard was used primarily as an impact substitute, providing additional creativity on the left flank. His performances were generally well received, with local media noting his willingness to take on defenders and his improved match sharpness. Although he did not become a regular starter, he contributed valuable depth to PSV’s attacking options during their push for domestic honours.

Royale Union Saint-Gilloise, where he scored the equaliser for Anderlecht in the last minutes of the game, which ended in a 2–2 draw. Hazard was an important part of Anderlecht’s 2023–24 title ambitions, adding much needed experience to
Brian Riemer’s team. This meant Anderlecht had suffered a huge blow to their title ambitions on 14 April 2024, when Hazard tore his ACL during a play-off match against then-league leaders Union SG. In that same game Hazard’s substitute
Francis Amuzu scored a dramatic winner. But Anderlecht missed out on the title, with many believing Hazard’s injury played a big part in that. On 27 December 2024, Hazard made his return after eight months against
FC Dender, coming on as a substitute for
Yari Verschaeren. On 19 January 2025, Hazard returned to the starting XI after 280 days in a
Jupiler Pro League game against
KV Kortrijk. The game ended 2–0 in favour of Anderlecht, with Hazard scoring the opener from a direct free kick. On 2 March 2025, in the Belgian Clásico against
Standard de Liège, Hazard scored a curling shot from outside the box into the top right corner, putting his team 1–0 up at
