Hieronymus Andreae, or Andreä, or Hieronymus Formschneider, was a German woodblock cutter ("formschneider"), printer, publisher and typographer closely associated with Albrecht Dürer. Andreae's best known achievements include the enormous, 192-block Triumphal Arch woodcut, designed by Dürer for Maximilian I, Holy Roman Emperor, and his design of the characteristic German "blackletter" Fraktur typeface, on which German typefaces were based for several centuries. He was also significant as a printer of music.

Woodcut is a relief printing technique in printmaking. An artist carves an image into the surface of a block of wood—typically with gouges—leaving the printing parts level with the surface while removing the non-printing parts. Areas that the artist cuts away carry no ink, while characters or images at surface level carry the ink to produce the print. The block is cut along the wood grain. The surface is covered with ink by rolling over the surface with an ink-covered roller (brayer), leaving ink upon the flat surface but not in the non-printing areas.
