Matthäus Merian (25 March 1621 – 15 February 1687) was a Swiss engraver and portrait painter.
He was born in Basel as the eldest son of Matthäus Merian the Elder and his first wife Maria Magdalena née de Bry; like his father he became an engraver.
He is documented as having served Carl Gustaf Wrangel as an importer of wine and other luxury goods and is known for his portraits.
[1] After the death of his grandfather Johann Theodor de Bry, his father took over his publishing house in Frankfurt, where Matthew the Younger became a pupil of Joachim von Sandrart.
In 1647 he took part as a political agent and representative of several princes at the Peace Congress in Nuremberg, of whose participants he made portraits.
