FC Seoul () is a South Korean professional football club based in Seoul that competes in the K League 1, the top flight of South Korean football. The club is owned by GS Sports, a subsidiary of GS Group. Since 2004, FC Seoul have played its home games at the Seoul World Cup Stadium in Seoul's Mapo District.
The club was founded as Lucky-Goldstar Football Club in 1983, by the LG Corporation, and was later renamed as LG Cheetahs in 1990. Due to the K League decentralization policy in 1996, the club was relocated to the Seoul's satellite city of Anyang for eight years, before returning to Seoul in 2004. FC Seoul have won six K League titles, two FA Cups, two League Cups and one Super Cup. Internationally, the club reached the AFC Champions League final on two occasions, in 2001–02 and 2013.
FC Seoul is one of the most successful and popular clubs in the K League 1, with financial backing from the GS Group. In 2012, the club was evaluated as the most valuable football brand in the K League. Their main rivals are Suwon Samsung Bluewings, with whom they contest the Super Match.
To establish a professional football club, the Lucky-Goldstar Group had a preparatory period since 1982 and requested that the franchise be located in Seoul. In the 1984 season, the club finished seventh out of eight clubs. The club fared better in the 1985 season, winning the league title with the help of Thai international Piyapong Pue-on, who was the league's top scorer as well as the top assist provider.
As a result, 3 clubs were evicted from Seoul to other cities. This entailed the move of the LG Cheetahs to the Anyang Sports Complex in the city of Anyang, a satellite town of Seoul, 21 km away. The club was now known as the Anyang LG Cheetahs. In the upcoming years, a solid base of supporters was formed, and it established a strong league rivalry with the Suwon Samsung Bluewings. This rivalry was partly fueled by the fact that LG Group and Samsung, which owned the Suwon club, were also considered rivals in the business world, especially in electronics. The club continued to grow and in 2000, they won their third Championship, behind the firepower of striker Choi Yong-Soo.
FC Seoul's 2009 AFC Champions League campaign began with a 2–1 win over Indonesian side Sriwijaya FC. In the next three games, FC Seoul obtained only one point in the matches against Gamba Osaka and Shandong Luneng. However, Seoul then defeated the title holders Gamba Osaka and qualified to the round of 16 after Sriwijaya's unexpected victory over Shandong Luneng. On June 24, 2009, FC Seoul beat Kashima Antlers 5–4 after penalties after a 0–0 draw in the round of 16 clash and advanced to the quarter-finals, but were beaten 4–3 on aggregate by Qatari club Umm Salal. FC Seoul's appearance in the AFC Champions League was its first since the Asian Club Championship era.
The Şenol Güneş era ended on November 25, 2009, with the manager returning to Trabzonspor.
FC Seoul recorded an attendance of 60,747 against Seongnam FC on May 5, 2010, at Seoul World Cup Stadium, which is the highest single-game attendance record in South Korean professional sports history. FC Seoul also recorded the single season (League, K League Championship, and League Cup) highest total attendance record – 546,397, and the single regular & post season (League and K League Championship) highest average attendance record of 32,576.
On August 25, 2010, FC Seoul beat Jeonbuk Hyundai Motors 3–0 to become the 2010 League Cup winners. FC Seoul were also crowned K League champions by defeating Jeju United 4–3 on aggregate in the K League Championship final, thus achieving their first "double" in the club's history. The crowd of 56,769 in the second leg also set the record of the highest attendance in K League Championship history.
On December 13, 2010, FC Seoul wanted to extend Vingada's one-year contract but FC Seoul and Vingada could not come to an agreement over the salary conditions, resulting in Vingada returning to Portugal.
On June 21, 2016, FC Seoul appointed Hwang Sun-hong as their eleventh manager in the club's history. On November 6, 2016, FC Seoul won their sixth K League title after defeating Jeonbuk Hyundai Motors 1–0 in the final round of the season.
On October 11, 2018, Choi Yong-soo was appointed as the twelfth manager in the club's history, having previously managed the club between 2011 and 2016.
During the 2020 season, FC Seoul lost five consecutive games for the first time in 22 years. Following a new departure by Choi Yong-soo, three different caretakers took turns managing the team, with Park Hyuk-soon replacing Kim Ho-young after just a month and guiding the team to the end of the K League season, which they finished in ninth place, before being substituted by Lee Won-jun; under his management, the team made a promising start in the group stage of the 2020 AFC Champions League, even obtaining a 5–0 victory against Thai outfit Chiangrai United, but then proceeded to lose all of their last three matches, thus being eliminated from the tournament. A difficult season was made even more devastating by the death of defender Kim Nam-chun on October 30, 2020, just a day before their last K League 1 fixture against Incheon United.
In the 2024 K League 1 season, the club broke average attendance records due to a recovery of the league itself and the signing of Jesse Lingard, as the club finished in the top half of K League 1 for the first time since 2019 and qualified for the 2025–26 AFC Champions League Elite. Lingard was appointed captain ahead of the 2025 season, but left the club after a disappointing sixth-place league finish, scoring against A-League Men side Melbourne City in the Champions League in his last game for Seoul.
Other major rivalries include Jeonbuk Hyundai Motors (Jeonseol Match) and Incheon United (Gyeongin Derby). In an away match versus Incheon in May 2024, the home fans at the Incheon Football Stadium threw water bottles at Seoul players.
Fans of FC Anyang, a phoenix club that was founded in Anyang since the departure of Anyang LG Cheetahs, feel great animosity towards FC Seoul and a willingness to get their revenge on the pitch, with Anyang's fans lighting flares in a show of defiance in a 2017 Korean FA Cup match versus FC Seoul. Anyang's first-ever appearance in the 2025 K League 1 season allowed them to play against FC Seoul in a league match for the first time in the "Relocation Derby."
In the past, FC Seoul played at Daejeon Stadium, Cheongju Stadium, Cheonan Oryong Stadium (1987–1989), Dongdaemun Stadium (1990–1995), and Anyang Stadium (1996–2003).
There has also been different club mascots representing different periods. Former mascots were a bull and a cheetah. The club's current mascot, introduced in 2004, is named "SSID".
The "SSID" stands for Seoul & Sun In Dream. In the 2018 season, FC Seoul added another mascot, "Seoul-i".
A special crest for the club's 20th anniversary was used in 2003. The current crest has been used since 2004.
FC Seoul wore both red kits and yellow kits in home matches from 1984 to 1985.
From 1988 to 1994, the club's home shirt's main colour was yellow, same as the Lucky-Goldstar Group's company colour at the time.
In 1995, Lucky-Goldstar Group pushed ahead with corporate identity unification and the company colour was changed to red. As a result, FC Seoul's jersey colour was changed from yellow to red as part of the unification project.
From 1999 to 2001, FC Seoul wore red and blue stripes but returned to all red in the 2002 season and In 2005, FC Seoul changed to red and black stripes and this colour has been in use since.
In June 2016, FC Seoul released the 1984–1985 retro jersey to commemorate foundation of the club and the first K League title.
