Meridan Plains is a locality on the north-western edge of the Caloundra urban area in the Sunshine Coast Region, Queensland, Australia.

A large portion of the western boundary follows the Mooloolah River, while a small section aligns with the Bruce Highway.

Meridan Plains is named either using a corruption of a Kabi language word meaning place of kangaroos or dingoes, or after the birthplace of John Westaway in Devonshire, England.

[2][5][6][7]In early 1861 the tender of Edmund Lander was accepted, by the Commissioner for Crown Lands, for the 25-square-mile (65-square-kilometre) pastoral run of Mooloolah Plains in the Wide Bay and Burnett District.

[9] Lander went on to select 80 acres (32 hectares) in 1869 on the main coach road between Brisbane and Gympie at the Mooloolah Bridge.
