Cleland National Park, formerly Cleland Conservation Park, is a protected area located in the Adelaide Hills, South Australia about 22 kilometres south-east of the Adelaide city centre. It conserves a significant area of natural bushland on the Adelaide Hills face, including Mount Lofty Summit and Waterfall Gully. Formerly a conservation park, Cleland was combined with the bordering Eurilla Conservation Park in November 2021 when it was upgraded to the status of national park.
