Caladenia rosella, commonly known as the rosella spider orchid, is a plant in the orchid family Orchidaceae and is endemic to south-eastern Australia. It is a ground orchid with a single hairy leaf and a single scented pink flower. Although it may have had a wider distribution in the past, the total number of plants in 2000 was estimated to be 120 in four populations in Victoria. There is a single record from New South Wales but the orchid is classified as "extinct" in that state.
