Native to south-western Canada (i.e. British Columbia), western USA (i.e. Idaho, Oregon, Washington, New Mexico, Texas, Arizona, California, Nevada and Utah) and northern Mexico.
This species is widely naturalised in south-eastern Australia. It is widespread and common in New South Wales, the ACT and the western and central parts of Victoria.
Common fiddle-neck (Amsinckia intermedia) is a mainly found as a weed of cultivated land and disturbed sites in south-eastern Australia, however it may also invade pastures and natural vegetation.
It is sometimes regarded as an environmental weed in Victoria (e.g. in the Goulburn Broken Catchment) and has also been recorded in conservation areas in inland New South Wales (e.g. in Kinchega National Park, in the south-west of the state, and in the Mount Canobolas State Recreation Area, in the central-western part of the state). In the Mount Canobolas State Recreation Area, common fiddle-neck (Amsinckia intermedia) has been reported growing in grassy woodlands, tall open forests and along disturbed creeklines.
