The Brownsea Island Scout camp was the site of a boys' camping event on Brownsea Island in Poole Harbour, southern England, organised by Lieutenant-General Baden-Powell to test his ideas for the book Scouting for Boys. Boys from different social backgrounds participated from 1 to 8 August 1907 in activities around camping, observation, woodcraft, chivalry, lifesaving and patriotism. The event is regarded as the origin of the worldwide Scout movement.

Brownsea Island is the largest of the islands in Poole Harbour in the county of Dorset, England. The island is owned by the National Trust with the northern half managed by the Dorset Wildlife Trust. Much of the island is open to the public and includes areas of woodland and heath with a wide variety of wildlife, together with cliff top views across Poole Harbour and the Isle of Purbeck.
