Chloethiel Woodard Smith, FAIA (February 2, 1910 – December 30, 1992) was an American modernist architect and urban planner whose career was centered in Washington, D.C. She was the sixth woman inaugurated into the American Institute of Architects College of Fellows and at the peak of her practice led the country's largest woman-owned architecture firm.

Early in her career, Smith worked for the Federal Housing Authority and in the 1940s for Berla & Abel.

[2] Smith was responsible for significant project commissions and was selected to serve on various committees that influenced the shaping of post-World War II Washington, D.C.

She completed several projects in the redevelopment, including Capitol Park, Harbour Square, and Waterside Mall, and developed a proposal for a bridge with shops and restaurants spanning the Washington Channel that was inspired by the Ponte Vecchio in Florence, Italy.

Her name is not as well known by the general public as those of her contemporaries, yet she is considered to be a master whose successful career spanned five decades.
