Matilda Nildén

AIK In the summer of 2021, top-flight club AIK recruited Nildén. She made her Damallsvenskan debut in August 2021 at the age of 16 and went on to play in ten games in her first season for AIK. She also spent the end of 2021 on loan in the Elitettan for Bollstanäs SK alongside multiple other young players from AIK. She scored her first Damallsvenskan goal in 2022, in a loss to Nildén's future club BK Häcken. She started a total of 17 matches as AIK were relegated down to the Elitettan after finishing the 2022 Damallsvenskan in last place. Goalscoring would prove to be a common trend throughout the season for Nildén, who scored 23 times across 25 matches. She finished in second place in the Elitettan goal leaderboard, just behind Adelisa Grabus. In September 2023, she recorded a hat-trick against Trelleborgs FF to secure a top 3 finish in the league; AIK would reach even greater heights, winning the Elitettan title several games early, finishing the season undefeated,

BK Häcken Nildén's performances for AIK caught the eye of many clubs, including multiple in the Damallsvenskan. On 9 March 2024, she registered a debut goal in a cup match against Växjö DFF within only a few minutes of entering the game. She scored her first league goal for the club in May 2024, netting the game-tying goal that sparked a late Häcken comeback against her former team, AIK. Over the rest of the season, Nildén struggled to earn significant playing time as Häcken finished the year as Damallsvenskan runners-up. However, she ended the season on a positive note, scoring two goals against another one of her former clubs, IF Brommapojkarna, to guarantee Häcken's second-place league finish.

The following year, Nildén kicked off the season with a bang, tallying two goals against Vittsjo in a 7–1 cup victory. She went on to start 11 of her 25 Damallsvenskan matches across the year. She helped Häcken win the 2025 Damallsvenskan title, the club's first since 2020. She departed from the club having recorded 48 appearances and 8 goals across two years of league competition. The move reunited Nildén with her sister, Amanda, as well as former Häcken teammates Hanna Wijk and Josefine Rybrink.

International career Nildén has played for the Swedish U17, U19, and U23 youth national teams.
