Ellen Key park, Public park in Östermalm, Stockholm, Sweden.

Ellen Key Park covers 0.5 hectares between Karlavägen and Birger Jarlsgatan on Östermalm, bordered to the south by Borgarskolan. Three crosswise granite walls, half a metre high with limestone copings, divide it into three park rooms, and a low granite wall runs along its western edge. The Nordic Classical layout is well preserved, and the pond and planting by Sigrid Fridman's 1953 Ellen Key statue were renovated in 2006.

The park was established in the 1930s as part of Stockholm's urban renewal efforts and named after writer Ellen Key. Its creation during this period reflected a push to expand green spaces in this central district.

The park was called Jarlaparken until the 2000s, when it was renamed after Ellen Key. In 1953 Sigrid Fridman's statue of Key was placed in the eastern part facing Karlavägen, and the pond and planting around it were renovated in 2006.

The park is easily accessible by bus and metro, with several stops near the entrance making arrival straightforward. The pathways are well maintained and clearly marked, so visitors can move around without difficulty.

Though named after a writer involved in the women's movement, many visitors pass through without knowing much about Ellen Key's role in Swedish society. The space quietly commemorates her contributions to education reform and social change.
