Pelican Lagoon is a seawater lagoon in the Australian state of South Australia located on the north coast of Kangaroo Island about 18.7 kilometres (11.6 mi) south east of Kingscote. It was named by Matthew Flinders on 4 April 1802 after the large population of pelicans present in its waters and adjoining shorelines. Its role as fishery hatchery had been identified by the early 20th century with the result that fishing in its waters has been restricted in varying degrees. Since 1971, the entire lagoon has been part of a marine protected area known as the American River Aquatic Reserve where all fishing and the collection of marine organisms is prohibited.

Pelican Lagoon is a seawater lagoon located about 2.9 kilometres (1.8 mi) south of American River and about 18.7 kilometres (11.6 mi) south east of Kingscote. The lagoon is bounded by Dudley Peninsula to the east, the main body of Kangaroo Island to the west, an isthmus connecting the above-mentioned bodies of land to the south and an unnamed peninsula to the north that separates it from Eastern Cove. The lagoon is connected to Eastern Cove in Nepean Bay by an inlet named American River. Hog Bay Road which is the main road connecting Penneshaw to Kingscote passes on the east and south sides of the lagoon.

The lagoon itself consists of two branches - one on the east side and the other on the west side which was described as being the ‘southern branch’ by Flinders in 1802. The lagoon is drained of water by tidal flow via a narrow channel of 3 to 5 metres (9.8–16.4 ft) in depth and which passes through the west branch in order to reach the east branch. The tidal flow is reported as being as high as 3 knots (5.6 km/h; 3.5 mph).
