Greyfield, Colonial Revival estate in Camden County, US.

Greyfield is a Colonial Revival house built between 1901 and 1905 for Margaret Carnegie Ricketson and Oliver Ricketson on Cumberland Island. The National Register listing covers 203 acres and includes six contributing buildings and four contributing structures, among them the main house, which has served as the Greyfield Inn since 1962.

Margaret and Oliver Ricketson built the house at the start of the 1900s as the family expanded their presence on Cumberland Island. The building was added to the National Register of Historic Places in 2003 to recognize its architectural importance.

The house takes its name from Gray's Field, the site name recorded in 1900, which came from planter John W. Gray, who bought a 500-acre tract there in 1825. The land had earlier held a home built in the early 1800s by Martha Nightingale, a daughter of Nathanael Greene, and her husband. The Carnegie family still owns and manages the inn.

Greyfield Inn is the only hotel on Cumberland Island, reached by ferry from St. Marys; the inn runs its own boat transfer for guests. The 203-acre NRHP-listed estate includes six contributing buildings and four contributing structures, and the Carnegie family still owns and manages the inn. Book well ahead, as rooms are limited and the island has no other lodging.

The house stands on a site called Gray's Field in 1900, named for John W. Gray, a Jekyll Island planter who bought a 500-acre tract there in 1825. That tract, the Springs Plantation, had held an early 1800s house built by Martha Nightingale, a daughter of Nathanael Greene, and her husband.
