The 2021 Racing Louisville FC season was the club's first season of play. Racing Louisville competed in the National Women's Soccer League, the top flight of professional women's soccer in the United States.
Racing Louisville FC was announced on October 22, 2019, as an NWSL expansion team set to begin play in the 2021 season. Former Sky Blue FC head coach Christy Holly was named as Racing Louisville FC's first head coach on August 12, 2020. The club proceeded to build their roster through a combination of free agent signings, a trade with Chicago Red Stars for Savannah McCaskill and Yà «ki Nagasato in exchange draft protection, the 2020 NWSL Expansion Draft, and the 2021 NWSL Draft. Since the opening of the season, Racing also added English internationals Gemma Bonner and Ebony Salmon, former North Carolina Courage defender Sinclaire Miramontez, and Dutch international Nadia Nadim.
Holly was fired for cause on August 31, 2021, and the club named Mario Sanchez, head of the club's youth academy and former collegiate coach, as the interim head coach.
