Milton Grigg (1905–1982) was a Virginia, USA, architect best known for his restoration work at Colonial Williamsburg and Monticello. In his career as an independent architect in Charlottesville, he worked as a modernist within the Jeffersonian tradition. K. Edward Lay, author of The Architecture of Jefferson County, called Grigg "one of the premier architectural restoration/preservationists of his time – always with an inquisitive mind on the forefront of architectural inquiry".[1]
