Adam Stefan Lundkvist

Adam Lundkvist made his senior debut for IF Elfsborg in 2013, having come through the club's academy after arriving from Nyköpings BIS. He went on to make 110 league appearances for Elfsborg and scored three goals for the club between 2014 and 2016, including one in a 2–0 win over Kalmar FF in August 2014. Elfsborg won the Svenska Cupen in 2013–14, though Lundkvist did not feature in the final.

In April 2018, he left for Major League Soccer side Houston Dynamo, spending part of that first season on loan at USL Championship club Rio Grande Valley FC. With Houston he won the U.S. Open Cup in 2018, providing two assists in the competition, including a decisive one against Minnesota United. He also missed a month after a knee injury in September 2021.

Austin FC brought him in during 2023, paying Houston $500,000 in General Allocation Money for the move, and Lundkvist made 23 league appearances before joining BK Häcken on a free transfer in January 2024 on a three-year deal. He has since won the Svenska Cupen again, this time with Häcken in the 2024–25 season.

Internationally, Lundkvist earned two caps for Sweden, debuting on 6 January 2016 in a 1–1 friendly draw with Estonia, and he started all three group-stage matches for Sweden at the 2016 Summer Olympics.
