Fremont Island, at 14 square miles (36 km2), is the third largest island within the Great Salt Lake in Utah, USA. Antelope Island, at 42 square miles (110 km2) in area, is the largest island within the Great Salt Lake.
There are certain plant species that occur on Fremont Island, and there is historic evidence that some species that were earlier documented to occur on the island are no longer present. For example, explorers who visited this island in the mid-1800s noted the presence of abundant "onions" which they identified as Calochortus luteus. However, this name was applied to plants that were later renamed as other species. While it is unlikely that the California endemic C. luteus occurred on Fremont Island, it is clear that some species of Calochortus once present is now extinct.
At least one permanent family has lived on Fremont Island. Kate and Uriah Wenner and their children lived on the island for several years prior to the death of Uriah in 1891.
Fremont Island is privately owned and permission is required for access. The island has two landing strips suitable for landing small planes on the island.
