Harvey Slocum (October 23, 1887 – November 11, 1961) was an American civil engineer and dam-building expert, known primarily for his part in the construction of Grand Coulee Dam in the United States and the Bhakra Dam in India.
Slocum started out as a labourer in a steel mill and rose to the position of construction superintendent of the Grand Coulee Dam.
Slocum joined the Bhakra Dam construction project as chief engineer in 1952 and imprinted on it his own distinctive style of working. He was a flamboyant personality who drove a current model powder blue cadillac convertible; not expected of an engineer in those times in India.
Slocum died in New Delhi at age 74.
