Abraham Bloemaert was a Dutch painter and printmaker in etching and engraving. He was initially working in the style of the "Haarlem Mannerists", but in the 16th century altered his style in line with the new Baroque style that was then developing. He mostly painted history subjects and some landscapes. He was an important teacher, who trained most of the Utrecht Caravaggisti, at least for a period.

Bloemaert was born in Gorinchem, Habsburg Netherlands, the son of the architect Cornelis Bloemaert I, who moved his family to Utrecht in 1575, where Abraham was first a pupil of Gerrit Splinter (pupil of Frans Floris) and of Joos de Beer. From the age of 15 or 16, he then spent three years in Paris from 1581–1583, studying six weeks under a Jehan Bassot (possibly Jean Cousin the Younger) and then under a Maistre Herry. While in the School of Fontainebleau he received further training from his fellow countryman Hieronymus Francken. He returned to Utrecht in 1583, just before the French Wars of Religion began, which destroyed much of the work at the Chateau of Fontainebleau.

When his father was appointed city architect (Stads-bouwmeester) in Amsterdam 1591 he accompanied him there, and on his father's death in 1593 returned finally to Utrecht, where he set up a workshop and in 1594 became dean ("deken") of the "zadelaarsgilde", as from 1367 the painters were included in the saddlemaker's guild, with no Guild of St. Luke of their own. In 1611, along with the two other leading Utrecht painters, Joachim Wtewael and Paulus Moreelse, he was one of the founders of the Utrecht Guild of Saint Luke (St Lucas-gilde) a new Utrecht painters' guild, and became its deken in 1618. Many of Bloemaert's paintings were commissioned by Utrecht's clandestine Catholic churches. He died in Utrecht.

Among his many pupils were his four sons, Hendrick, Frederick, Cornelis, and Adriaan (all of whom achieved considerable reputation as painters or engravers).
