Pietro Ruga (c. 1772 - 1850) was an Italian engraver, printmaker, furniture designer, and architectural draftsman active in Rome during the late 18th and early 19th centuries. Ruga was born in Rome, Italy. He is best known today for his architectural views of Italian, in particular Roman, monuments, furnishings, and antiquities. There are only two maps attributed to Ruga, both tourist pocket plans of Rome, dating to the 1820s. Pietro Ruga the engraver should not be confused with Pietro Ruga Romano, who lived in Rome at the same time and taught civil law at the Sapienza.
