Patrick Charles Keely (August 9, 1816 — August 11, 1896) was an Irish-American architect based in Brooklyn, New York, and Providence, Rhode Island. He designed nearly 600 churches and hundreds of other buildings for the Catholic Church or Catholic patrons in the United States and Canada, particularly in New York City, Boston and Chicago in the later half of the 19th century. He designed every 19th-century Catholic cathedral in New England. Several other church and institutional architects began their careers in his firm.
