Lithospermum arvense (Field Gromwell, Corn Gromwell, Bastard Alkanet) is a flowering plant of the family Boraginaceae. It is also known as Buglossoides arvensis.

It is native to Europe and Asia, as far north as Korea, Japan and Russia, and as far south as Afghanistan and northern Pakistan. It is known in other places as an introduced species, including much of North America and Australia. The European Union has granted the refined oil of the seed of Buglossoides arvensis novel food status and some farmers are growing it.
