Luyckx (pronounced [lœyk(s)] ) is a Dutch patronymic surname based on an archaic spelling of the given name Luuk/Luc, short forms of Lucas.[1] The name has a myriad of spellings, all pronounced the same. While in Belgium Luyckx is by far the most common (3433 people in 2008),[2] in the Netherlands the forms Luijkx, Luijks, Luijk, Luik and Luijckx are more prevalent.[1] For some families the name may be toponymic instead, referring to an origin in Luik, the Dutch name of Liège.[1] This is generally the case for forms like Van Luijk, Van Luik and de Luyck.[3] People with these surnames include:
