Murphys Grammar School is a historic school building in Murphys, California. Built in 1860, the school was the first public school in Murphys. The school was designed in a vernacular Greek Revival style, which was popular at the time of its construction; its design includes a cornice held up by square pilasters, a pedimented gable, and a cupola over the entrance with its own cornice and square pilasters. The school operated continuously from its opening until it closed in 1973; at the time of its closing, it was the longest continuously running school west of the Mississippi River.
