Mountain Rest is a historic religious summer retreat on Wildwood Lane, off Spruce Corner Road in Goshen, Massachusetts. Built in the first decade of the 20th century, it served as a retreat for Christian missionaries to foreign countries during periods of furlough in the United States, and as a training facility for future missionaries. The camp was listed on the National Register of Historic Places in 1983. The camp closed in 1970, and in 1987 the complex was converted to condominiums.
