Flowerpot Island is an island in Georgian Bay, in the Canadian province of Ontario and is a part of Fathom Five National Marine Park. The island spans 2.1 kilometres (1.3 mi) from east to west, and 1.5 kilometres (0.93 mi) from north to south, and has a total area of 2 square kilometres (490 acres). The name of the island comes from two rock pillars on its eastern shore, which look like flower pots. A third flowerpot once stood, but tumbled in 1903.
