William F. Curlett (County Down, Ireland, March 3, 1846 – January 21, 1914, San Francisco) and Alexander Edward Curlett (called Aleck) (San Francisco, February 6, 1881 – September 5, 1942) were a father-and-son pair of architects. They worked together as partners under the name of William Curlett and Son, Architects from c. 1908–1916. Aleck Curlett partnered with Claud Beelman as Curlett & Beelman (1919–1932).
The San Francisco firm of Curlett, Eisen, & Cuthbertson, Architects, was active in the 1880s; it designed the Los Angeles County Courthouse in 1887. In 1888, the firm occupied Room #41 of the Downey Block. (See Los Angeles, California, City Directory, 1888, p. 768.)
