Theodor Galle (baptized July 16, 1571 in Antwerp; buried there December 18, 1633) was a Dutch copper engraver of the early baroque period.
The son of Philipp Galle and brother of Cornelius Galle the Elder, after an apprenticeship with his father, went to Rome, where he studied ancient monuments. He published the results under the title "Imagines ex antiquis marmoribus, numismatibus et gemmis expressae". Later he went back to Antwerp to trade in copper engravings. In addition to copies of Peter Paul Rubens, he also made his own designs, which he compiled under the titles "Speculum illustrium virginum" and "Marienleben".
