Naval Security Group Activity, Winter Harbor was a radio station of the United States Navy that operated from 1935 to 2002.

In the early 1930s, Otter Cliffs Radio Station on Mount Desert Island was literally falling apart.John D. Rockefeller, Jr., then developing the infrastructure of Acadia National Park, sought to locate the park's main loop road through the Otter Cliffs area. The Navy was willing to meet Rockefeller halfway on the removal of the radio station from Otter Cliffs, agreeing to relocate if a suitable site could be found on the coast within 50 miles (80 km) of Otter Cliffs. Big Moose Island, at the tip of Schoodic Peninsula about 5 miles (8.0 km) across the mouth of Frenchman Bay from Otter Cliffs, was determined to be an ideal location for the relocated radio station, and agreement was reached between the Navy, Interior Department, and Rockefeller for the relocation.

Rockefeller, wishing the station's buildings to be compatible with others designed for the park, retained Grosvenor Atterbury, the New York architect who designed the park's gatehouses, to come up with plans for the radio station. Atterbury's plan for the new station included a beautiful residence hall similar to Mr. Rockefeller's residence at Seal Harbor. Artisans from all over the world contributed to the project. This building, and the adjacent power station which was also designed by Atterbury, were listed on the National Register of Historic Places in 2013.

On 28 February 1935, the U.S. Navy Radio and Direction Finding Station Winter Harbor was officially commissioned with Chief Radioman Max Gunn in charge of a complement of 11 personnel.

The station's name has changed several times over the years. In 1944, it was changed to Supplementary Radio Station, U.S. Naval Radio Station Winter Harbor. In 1950, it became known as U.S. Naval Radio Station (Receiver). The present station name, Naval Security Group Activity, Winter Harbor, became official on 9 June 1958.
