John McArthur Jr. (1823–1890) was a prominent American architect based in Philadelphia. Best remembered as the architect of the landmark Philadelphia City Hall, McArthur also designed some of the city's most ambitious buildings of the Civil War era. Few of his buildings survive.

Upon its completion, Philadelphia City Hall, built between 1874 and 1901, was the tallest occupied building in the world and the world's third-tallest building structure after the Washington Monument, which is 7 feet / 2.1 meters taller, and the Eiffel Tower, which is 515 feet / 157 meters taller. It remains the world's tallest all-masonry occupied building.
