Östermalm city district, Residential district in central Stockholm, Sweden.

Östermalms stadsdelsområde was a Stockholm district area until 30 June 2023, when it merged with Norrmalm and Vasastaden into Norra innerstadens stadsdelsområde. It covered Östermalm (except a small part by Roslagstull), Hjorthagen, Gärdet, Djurgården and Norra Djurgården, and had 83,057 inhabitants in 2021. Östermalm itself holds the Stureplan nightlife cluster and the 1888 Östermalms Saluhall market hall.

The area was originally known as Ladugårdslandet in the 1600s and served as royal pasture land for livestock. During the major urban development of the 1880s, the farmland transformed into a modern residential neighborhood.

Östermalmstorg hosts a sculpture group by Willy Gordon that has been debated among residents. Across the square stands the Östermalms Saluhall market hall from 1888, called the Stockholmers' "temple of eating". Near the Elim Church, the Storken pharmacy is considered Sweden's most culturally and historically important pharmacy.

The Östermalmshallen Market Hall has been a shopping destination since the late 1800s, offering fresh seafood, vegetables, meat, and cheese. The district is walkable and allows you to move between different neighborhoods at your own pace.

The 1912 Olympic Stadium in Norra Djurgården was built for the 1912 Summer Olympics and still hosts events today. It is the oldest Olympic venue still in regular use. The brick stadium was designed by Torben Grut and held the 1912 Games' opening and closing ceremonies.
