John Mead Howells FAIA (/ˈhaʊəlz/ HOW-əlz; August 14, 1868 – September 22, 1959) was an American architect.

Born in Cambridge, Massachusetts, the son of author William Dean Howells, he earned an undergraduate degree from Harvard University in 1891 and completed further architectural studies there in 1894 before studying at the École des Beaux-Arts, in Paris, where he earned a diploma in 1897.

The partnership designed such works as St. Paul's Chapel at Columbia University and Stormfield, an Italianate villa commissioned by Samuel Clemens,[1] a longtime friend of his father.

[2] Ending the partnership in 1916, Howells would focus his practice on office buildings in the Art Deco style, some of which he completed with Raymond Hood, whom he had met during his time at the École, and whom he had invited to become a partner when he was selected to enter the Chicago Tribune building competition in 1922.

Howells also designed the Beekman Tower in New York and the plan for the University of Brussels in Belgium in 1922 at the request of U.S. Secretary of Commerce Herbert Hoover.
