McKim, Mead & White was an American architectural firm based in New York City. The firm came to define architectural practice, urbanism, and the ideals of the American Renaissance in fin de siècle New York.

The firm's founding partners, Charles Follen McKim (1847–1909), William Rutherford Mead (1846–1928), and Stanford White (1853–1906), were giants in the architecture of their time, and remain important as innovators and leaders in the development of modern architecture worldwide. They formed a school of classically trained, technologically skilled designers who practiced well into the mid-20th century. According to Robert A. M. Stern, only Frank Lloyd Wright was more important to the identity and character of modern American architecture.
