Nashville SC

Prior to the arrival of Nashville's MLS team, the city had various soccer teams which played in the lower divisions of American soccer. The most notable teams were the Nashville Metros who played from 1989 until 2012 and Nashville FC, who played in the National Premier Soccer League (NPSL) from 2013 to 2016. The city also hosts two NCAA Division I men's soccer teams, the Belmont Bruins and Lipscomb Bisons. The Vanderbilt Commodores also played Division I men's soccer until the team's demise after the 2005 season. Prior to these teams, the Nashville Diamonds participated in the then-second division American Soccer League for one season in 1982.

The NPSL team, Nashville FC, was founded by a supporters group that intended to form a team as a fan-owned group. Chris Jones, Nashville FC's president, cited existing fan-owned clubs as inspiration for NFC's foundation, in particular the English club F.C. United of Manchester. In February 2014, the two groups merged to form a single club for the 2014 NPSL season. The club had two teams participating in the Middle Tennessee Soccer Alliance, Nashville's largest competitive adult league, and had partnered with the Tennessee State Soccer Association (TSSA), an organization with over 20,000 registered players in the Middle Tennessee area alone. The team played its matches at Vanderbilt Stadium. The NPSL club had ambitions of climbing the American soccer pyramid, with the reported target an entry into the then third-tier United Soccer League (USL; now known as the USL Championship) by 2017, and then ascension into the Division II North American Soccer League by 2020.

Nashville SC was founded in 2016, when the USL awarded a franchise to the founding ownership group of the club. An existing team at the time, Nashville FC subsequently sold its team name, logo, and color scheme to then new USL franchise, in exchange for a 1 percent equity stake in the USL team and a voting seat on its board. In August 2016, a group of Nashville business leaders led by Bill Hagerty formed the Nashville MLS Organizing Committee and began efforts to secure funding for an MLS stadium. The group fully supported the recently awarded Nashville SC, which began play in 2018. Both groups supported each other in their common vision to grow the sport in Tennessee. Former 2010 MLS Cup winning coach Gary Smith was announced as the team's first manager in April 2017.

In October 2017, the group unveiled their plans for a $275 million stadium and redevelopment project, which was approved by the city in November.

The formal bid to add an MLS franchise to Nashville began in January 2017. On March 4, 2017, businessman John Ingram, under the entity Nashville Holdings LLC, bought a majority stake in DMD Soccer, the ownership group of Nashville SC. Ingram also headed up the bid to bring an MLS franchise to Nashville, and the partnership between Ingram and Nashville SC was an effort to present a united front to MLS after Nashville was named one of ten finalist cities for four MLS franchises.

MLS officially awarded an expansion team to Nashville on December 20, 2017, and announced that they would join the league in 2020. Mike Jacobs and Ian Ayre was announced as the Nashville's first general manager and CEO respectively.

On February 10, 2018, Nashville SC competed in their first game; in preseason against Atlanta United FC. In the rain-soaked contest, Nashville was defeated by Atlanta, 3–1, in front of 9,059 spectators.

Nashville SC finished 4th in the Eastern Conference in their first season in the USL Championship. The team advanced to the Conference Semifinals in the playoffs, where they were defeated by Indy Eleven. In 2019, the final season in USL Championship, Nashville finished 2nd in the Eastern Conference regular season and advanced to the Conference Semifinals, losing to Indy Eleven 1-0 in front of 4,174 fans at First Horizon Park.

Nashville SC's inaugural MLS match was February 29, 2020, with the club hosting Atlanta United FC at Nissan Stadium. The game was played in front of 59,069, becoming the highest attended soccer event in Tennessee. Walker Zimmerman scored the team's first goal in the 2–1 loss. The inaugural season came to a halt on March 12, 2020, after only two games when the MLS suspended the season for thirty days due to the COVID-19 pandemic, then extended to until May 10, 2020. On June 10, MLS announced MLS is Back Tournament, but Nashville were unable to participate in the tournament due to multiple COVID cases on the team. Their next game was an August 12 win against FC Dallas. Nashville SC finished the 2020 regular season 8–8–7 with 32 points. They entered the MLS Cup playoffs in the play-in round defeating Inter Miami 3–0 and knocking off Toronto FC 1–0 in the first round, before being defeated by the eventual champions Columbus Crew in the conference semi-finals in extra time. The 2021 season saw Nashville perform well defensively, only allowing a tied for league-leading 33 goals and going undefeated at home. The 2021 team would also tie a league record for draws in a season at 18. Nashville returned to the playoffs, but was again eliminated in the conference semi-finals, this time by Philadelphia Union in a penalty shootout. 2022 saw both the opening of Geodis Park and Hany Mukhtar winning both the Landon Donovan MVP and Golden Boot awards after being a finalist for the former in the previous season. Mukhtar led the league with 34 goal contributions, nearly two thirds of Nashville's goals in 2022 and leading the team to a third consecutive playoff berth. Despite Mukhtar's success the club was eliminated in the first round of the playoffs by the LA Galaxy. The 2023 season saw a similar record to 2022, winning 13 matches in the regular season, then getting eliminated in the first round again, this time by Orlando City. Although, 2023 saw the inaugural League's Cup, a competition between the MLS and Liga MX. Nashville made a historic run to the final of that tournament, eliminating FC Cincinnati, Club America, Minnesota United, C.F. Monterrey, before facing the newly signed Lionel Messi and Inter Miami in the final, losing in the 11th round of penalties in a sold-out Geodis Park. During the cup, Nashville brought in Sam Surridge, an English striker from Nottingham Forest, who made an immediate impact scoring the equalizing goal against Club America to send the game into penalties. Surridge is now 2nd in NSC history in goals scored. 2024 saw a disappointing year, only winning 9 matches, finishing 13th in the east, and missing the playoffs. NSC was eliminated from the CONCACAF Champions Cup in the 2nd round by Inter Miami and did not make it out of the group stage of the League's Cup. After starting with a record of 3 wins, 4 losses, and 5 draws, Nashville SC fired their first manager Gary Smith. Rumba Munthali took over as an interim until July 3rd, when Nashville hired B.J. Callaghan as their next coach. 2025 started off great for the Boys in Gold, holding onto one of the longest unbeaten streaks across all competitions in MLS history, spanning 15 matches from April 26th to July 12th. With the new cup competition format for the MLS, Nashville SC could only participate in the U.S. Open Cup in 2025. NSC went on to win the 2025 U.S. Open Cup, beating Austin F.C. in the final. The match was played at Q2 Stadium, resulting in 2-1 contest with goals from Hany Mukhtar and Sam Surridge. This championship marks the first major professional sports championship in Tennessee history.
