Mjölkö or Mjölkön is an island in Österåkers municipality about 3 km east of Åkersberga. The island consists of around 120 residences and the number of residents during the 2000s has been few. The Mjölkö community association manages approximately 10 km gravel roads, several docks, and water areas around the island. The association also arranges midsummer celebrations and other social activities. The island is operated by Waxholmsbolaget.
The island's name is derived from that the mainland farmers used to have their cows on the island during the summer months and traveled there every day to milk them.
