Nobelparken, Urban park in Östermalm, Stockholm, Sweden.

Nobelparken is an urban park stretching along Strandvägen and the Djurgårdsbrunnsviken waterfront, combining a promenade with natural green spaces. Walking paths link areas with Nordic tree species, seating zones, and a nature play area featuring animal sculptures.

The park was long known as Ladugårdsberget, after the old royal barn Vädla that stood on the site. In 1911 the architect Ferdinand Boberg drew plans for a monumental Nobel Palace here, and in 1905 he had proposed a palace for Crown Prince Gustaf VI Adolf and Margareta of Great Britain and Ireland; neither was built. The name Nobelparken dates from 1912, when the park and the nearby street were named after Alfred Nobel.

The arboretum was planted by the Forestry Institute, which had its premises in the park's 1773 building from 1828 to 1916; the trees served as its teaching collection. The institute was founded by Israel af Ström, then superintendent of Djurgården, who initiated the plantation. Since 2011 the old institute building has housed the Israeli embassy.

Enter from Strandvägen or Dag Hammarskjölds väg; the park runs east as a narrow strip past Diplomatstaden. Paths are unpaved and mostly level, with benches facing Djurgårdsbrunnsviken. The tree collection is labelled, so allow time to walk the whole length.

The park is an arboretum with a specimen of nearly every tree species that grows wild in Sweden, except for the mountain birch, whose climate differs too much from the mountain regions. The planting was overseen by the Forestry Institute, which had its premises here from 1828 to 1916.
