Lauren Flynn

College career Flynn made 10 appearances as a freshman, primarily as a substitute, before the fall season was shortened due to the COVID-19 pandemic. Head coach Mark Krikorian then moved her from winger to center back in the spring portion of the season, where she started all five games alongside Emily Madril as the Seminoles reached the final of the NCAA tournament, losing to Santa Clara on penalties.

Flynn remained at Florida State as Brian Pensky, who formerly coached one of her sisters at Tennessee, replaced Krikorian in 2022. During her senior season, Flynn featured in attack for senior night against NC State and scored a hat trick to double her career scoring total. She then won her fourth consecutive ACC tournament.

Club career Utah Royals Flynn was drafted by expansion team Utah Royals with the 16th overall pick in the second round of the 2024 NWSL Draft. She was signed to a one-year contract with the option to extend an additional year. She made her professional debut on April 20, 2024, starting against Racing Louisville. She won NWSL Save of the Week after the May 25 game against the Kansas City Current for her last-ditch header to deflect Temwa Chawinga's shot on goal. However, her rookie season ended prematurely after she was diagnosed with bilateral compartment syndrome that was causing incessant pain in her calves. Utah placed her on the season-ending injury list on August 28, 2024, and she underwent surgery. Up to that point, Flynn had led the Royals in combined tackles and interceptions through 12 games, starting 10.

In September 2024, Utah exercised Flynn's contract option for 2025. The following season, after over nine months out of action, she returned to the pitch for the Royals on April 25, 2025, replacing an injured Claudia Zornoza in the first half of their 1–0 loss to the Houston Dash. She finished the season with 9 appearances, starting 6.

Dallas Trinity

On January 20, 2026, USL Super League club Dallas Trinity announced that they had signed Flynn before the spring part of the season. Flynn made her Super League debut on January 31, participating in a draw with Brooklyn FC to kick off the second half of Dallas' season. The following match, she scored her first USL Super League goal as Dallas beat Fort Lauderdale United FC, 4–0.

International career

Flynn was first called up to the United States national under-20 team in December 2021, arriving at training camp just after winning her first NCAA championship. She appeared in six of seven games for the team at the 2022 CONCACAF Women's U-20 Championship, where they shut out all their opponents to win the tournament. She was selected to the roster for the 2022 FIFA U-20 Women's World Cup, where they lost in the group stage. She played friendlies with the national under-23 team in 2023 and 2025.
