Volcxken Diericx (active 1570 – 1600) was a Flemish printmaker and publisher.
She was probably from Antwerp like her husband and about the same age. She was the widow of Hieronymus Cock with whom she founded the publishing business Aux Quatre Vents (The Four Winds), which she continued for thirty years on her own. From 1551 until Cock's death, the couple employed the engravers Pieter Breugel the Elder, Lucas and Joannes van Deutecum, Giorgio Ghisi, Cornelis Cort, Philips Galle, Maarten van Heemskerck, Lambert Lombard, Hans Vredeman de Vries, Michiel Coxcie and Frans Floris. Diericx is known for republishing these works as well as contracting Hendrik Goltzius during his first few years in Haarlem (1577–1582). She died in Antwerp and left over 1,600 copper plates and a large inventory of prints in her estate.
