William James Dodd (1862–1930) was an American architect and designer who worked mainly in Louisville, Kentucky from 1886 through the end of 1912 and in Los Angeles, California from early 1913 until his death. Dodd rose from the so-called First Chicago School of architecture, though of greater influence for his mature designs was the classical aesthetic of the Beaux-Arts style ascendant after the Chicago World's Columbian Exposition of 1893. His design work also included functional and decorative architectural glass and ceramics, furniture, home appliances, and literary illustration.

In a prodigious career lasting more than 40 years, Dodd left many extant structures on both east and west coasts and in the midwest and upper south, among the best known of these being the original Presbyterian Seminary campus (now Jefferson Community & Technical College), the Weissinger-Gaulbert Apartments, and the old YMCA building, all three in downtown Louisville. Also notable are his numerous residential and ecclesiastical designs still in use in Kentucky and Tennessee. In California, examples of his extant work include the Pacific Center and Hearst's Los Angeles Herald-Examiner Building in downtown Los Angeles and the San Gabriel Mission Playhouse south of Pasadena. Some of his earliest attributed designs may be found in Hyde Park, Illinois.
