Trifolium dubium, the lesser trefoil,[2] suckling clover,[3] little hop clover or lesser hop trefoil, is a flowering plant in the pea and clover family Fabaceae. This species is generally accepted as the primary plant to represent the traditional Irish shamrock.[4]

It is native to Europe, but can be found in many parts of the world as an introduced species.

It is probably an allotetraploid with 2n=32 that arose from the crossing of Trifolium campestre and T. micranthum.[5]
