Crataegus submollis, known as the northern downy hawthorn,[2] northern red haw,[2] Quebec hawthorn,[3] or hairy cockspurthorn,[4] is a species of hawthorn that grows to about 7 m in height[2] and typically carries large crops of red fruit.[1]

This species is closely related to C. mollis, but the two species have separate native ranges.[1] Amongst other differences between these two species, C. mollis has approximately 20 stamens, whereas C. submollis has approximately 10 stamens per flower.[1] Crataegus submollis is native to north-eastern North America, and has been introduced in Europe.[2]

The thorns are usually numerous and up to 7 cm in length.[2]
