The Rockefeller Cottage, also known as Indian Mound Cottage, is a house on Jekyll Island, Georgia. It is next to the Jekyll Island Club. It stands three stories high, and has a total of 25 rooms. There are nine bedrooms, nine bathrooms, and seven servant rooms. The house has many distinguishing features such as an elevator, a cedar-lined walk-in safe, and taps for hot and cold salt water on the bathtub in the master bedroom bath. Tours of the mansion are provided by the Jekyll Island Museum.

The house was built by Gordon McKay in 1892. McKay died in 1903 and the house was bought by William Rockefeller in 1905, who used it as a winter home. It was evacuated in 1942, along with the rest of the island. The house remained in the Rockefeller family until 1947, when the Jekyll Island Authority bought the property. It was open as a museum from 1950 until 1968, when it was closed for badly needed repairs. It is now a public museum. It was added to the National Register of Historic Places in 1971.

The house took its original name from a mound in the front yard. The mound was once thought to be an Indian burial ground for the Guale Indians, who were the earliest inhabitants of the island. The mound was later found to be a shell midden left by the Indians.
