Caladenia decora, commonly known as the Esperance king spider orchid, is a species of orchid endemic to the south-west of Western Australia. It has a single hairy leaf and up to three red, yellow and green flowers. It is a variable species, similar to the king spider orchid (C. pectinata) and sometimes hybridises with other species so that it can be difficult to recognise, but is one of the largest spider orchids found in Western Australia.
