Heinrich Wölfflin (; 21 June 1864 – 19 July 1945) was a Swiss art historian, esthetician and educator, whose objective classifying principles ("painterly" vs. "linear" and the like) were influential in the development of formal analysis in art history in the early 20th century. He taught at Basel, Berlin and Munich in the generation that saw German art history's rise to pre-eminence. His three most important books, still consulted, are ''Renaissance und Barock'' (1888), ''Die Klassische Kunst'' (1898, "Classic Art"), and ''Kunstgeschichtliche Grundbegriffe'' (1915, "Principles of Art History").
