Cornelis Abrahamsz. Bloemaert II (Utrecht, ca. 1603 – Rome, 28 september 1692) was a Dutch artists and engraver during the Golden Age who gained particular fame through his reproduction prints. He is the grandson of bouwmeester Cornelis Bloemaert I (ca. 1540-1593).
He was born the second son of his father Abraham Bloemaert and studied together with his father, his brothers Hendrick and Adriaen and his father's Apprentice, Gerard van Honthorst. Although he originally learned the painting trade, he mainly focused on printing technology, which he learned from Crispijn de Passe de Oude (I). In 1630 he went to Paris, where he made engravings for, among others Michel de Marolles‘ Temple des Muses. In 1633 he left for Rome.
His work can be recognized by the richness of the colors and the softness of the transitions between them. Among his pupils are Michel Natalis and Gilles Rousselet. Some of his better known engravings are Annibale Carracci‘s The Holy Family, Pietro da Cortona‘s Adoration of the Shepherds and Rubens‘ Meleager.
According to Houbraken, he travelled to Rome to make prints of many Italian Paintings. He was so successful in this that he stayed there until word reached him that his father wanted to see him one more time before he would die. However, he delayed his return so long that his father died and he remained in Rome until he died there himself. He was a member of the Bentvueghels with the bentname "Winter".
