Kvarnholmen is a peninsula on the western part of the Nacka Municipality, south-east of Stockholm, Sweden.
It is surrounded by the Saltsjön to the north and by the Svindersvik bay to the south.
The modern history of Kvarnholmen starts with the foundation of the mill Qvarnen Tre Kronor in 1897.
1922 the mill was bought by Kooperativa Förbundet, developing the peninsula into a mix of food industry sites and a residential area in the functionalist architectural style for the company's workers.
