Lloyd Bruce Wescott (November 21, 1907 – December 24, 1990) was an agriculturalist, civil servant, and philanthropist in New Jersey. Born and educated in Wisconsin, he moved to New York after college before settling in New Jersey where he served as a member of agricultural boards, chairman of the New Jersey State Board of Control of Institutions and Agencies, and founder and first president of the Hunterdon Medical Center. He was also a major fundraiser and donor of land that became Wescott Preserve in Hunterdon County. Novelist Glenway Wescott was his brother.
Wescott was born in 1907 on a dairy farm outside Farmington, Washington County, Wisconsin, the son of Bruce and Josephine Wescott. His elder brother Glenway was also born in Wisconsin in 1901. He graduated from high school in Ripon, Wisconsin and attended Ripon College. He then lived for several years in New York City.
In March 1935, Wescott married Barbara Harrison, the daughter of Francis Burton Harrison, Governor-General of the Philippines under Woodrow Wilson. In 1936 they purchased a 1,000-acre (4.0 km2) dairy farm along the Mulhocaway Creek in Union Township near Clinton in Hunterdon County, New Jersey. Mulhocaway Farm, as it was known, became the headquarters for the Artificial Breeding Association, a pioneer in the artificial insemination of dairy cows. In the 1950s, Mulhocaway Farm was acquired by the State of New Jersey under eminent domain in order to create the Spruce Run Reservoir.
