Calectasia gracilis, commonly known as blue tinsel lily, is a species of plant in the family Dasypogonaceae and is endemic to the south-west of Western Australia.

It was first formally described in 2001 by Gregory John Keighery from a specimen collected near Cape Riche by Russell Barrett and Kingsley Dixon.

It is scattered in the Stirling Range, Fitzgerald River and Frank Hann national parks, growing on quartzite sands, in mallee woodland or heath often over laterite or granite.
