Admiral Island is a manmade island and residential estate situated in Port Owen, which lies between the towns of Laaiplek and Velddrift on the West Coast region of South Africa.^[1] The area of the island is about 21 hectares, with a circumference of 3 km. The island is bounded on two sides by 2 km of private waterways and one side faces the Berg River. Admiral Island is a residential development with no commercial zones. Of the 191 plots on the island about two thirds are water-front stands.

The island was part of the original development of Port Owen. In 1999, the island was bought by a Belgium Consortium from the Owen Wiggins Trust Co. Ltd. and renamed Ile Plaisance. During 2004, the Belgium Consortium sold Ile Plaisance to a Group of Developers and it was renamed Admiral Island. ^[2]
