Calectasia intermedia, commonly known as blue tinsel-lily or eastern tinsel lily is a species of flowering plant in the family Dasypogonaceae, endemic to the border areas of western Victoria and south-eastern South Australia and flowering in early spring.

Calectasia intermedia is a rhizomatous perennial herb growing to a height of about 65 cm (25.5 in) as an undershrub.

It was formally described in 1856 by German botanist Otto Wilhelm Sonder, based on plant material collected by Ferdinand von Mueller in the Grampians in Victoria.

[4][5] The specific epithet (intermedia) is from the Latin intermedius "coming between", referring to its apparent intermediate appearance between C. cyanea and C. grandiflora, the only two other species recognised at the time.

[2] C. intermedia occurs from Bordertown in the far south-eastern corner of South Australia including the Calectasia Conservation Park,[6] east to the Grampians and Little Desert, south-western Victoria.
