Coffin Bay, originally Coffin's Bay, is a town at the southern extremity of the Eyre Peninsula, a wheat growing area of South Australia. At the 2016 census, Coffin Bay had a population of 611. The town is situated on the western side of the southern tip of Eyre Peninsula about 46 km from Port Lincoln. The population swells during holiday seasons to more than 4,000 people due to its proximity to the Coffin Bay National Park.
