Karoline Smidt Nielsen (born 12 May 1994) is a Danish former footballer who played as an attacking midfielder for Turbine Potsdam of the German Frauen-Bundesliga as well as for the Denmark women's national football team.
Smidt Nielsen joined Fortuna Hjørring from OB Odense in summer 2012.[1] She began playing in the boys' team at HPTI from being four years old, then played for B 1913 from 11 to 15, then joined OB where she played her first matches in the Danish Women's League.[2]
She was forced to retire in October 2022, following a series of injuries which restricted her to nine appearances for her German club Turbine Potsdam since joining them in 2018.[3]
In December 2012 Smidt Nielsen made her senior international debut as a second-half substitute for Pernille Harder in Denmark's 5–0 win over Mexico in São Paulo, Brazil.[4]
She was selected in national coach Kenneth Heiner-Møller's Denmark squad for UEFA Women's Euro 2013.[5]
Karoline's mother Lone Smidt Nielsen (née Hansen) is also a former international footballer, who played professionally in Italy.[6] [7]
