List of tallest lake islands

The following table includes the 30 tallest world islands located in a lake or reservoir. These lake islands are ranked by their topographic prominence, their maximum elevation above the surrounding water level.

All geographic coordinates are adjusted to the World Geodetic System of 1984 (WGS 84). North American topographic elevations are adjusted to the North American Vertical Datum of 1988 (NAVD 88). Use the OpenStreetMap link below to view the location of the high points of these tallest lake islands.
