Eliza Kennedy Smith (December 11, 1889 – October 23, 1964), also known as Mrs. R. Templeton Smith, was a 20th-century American suffragist, civic activist, and government reformer in Pittsburgh, Pennsylvania. Upon her death in 1964, The Pittsburgh Press described her as "a relentless, tenacious watchdog of the City's purse strings" who "probably attended more budget sessions over the years than anyone else in Pittsburgh either in or out of government".
