The Glynn County Georgia map covers Brunswick, the mainland coast, and the barrier-island communities known as the Golden Isles. Tidal rivers and marshes separate the urban port from St. Simons Island, Sea Island, Jekyll Island, and smaller protected coastal areas.
The U.S. Census Bureau estimated 87,599 residents on July 1, 2025, a 3.7 percent increase from the 2020 estimates base. Brunswick is the county seat and the only incorporated municipality.

An Original Georgia County on the Atlantic
Glynn County was created on February 5, 1777, as one of Georgia’s original eight counties. It includes mainland territory between major coastal rivers and a group of islands added to the county during its early history.
The modern county combines port industry, federal training facilities, seafood businesses, resort communities, historic sites, beaches, golf, and extensive salt marsh. That mixture gives the county a more varied economy and landscape than a typical coastal resort area.
Map Coverage and File Options
This Glynn County Georgia map set contains color, black-and-white, and outline A3 JPG files. The labeled versions support regional reference, while the outline file leaves space for coastal water, island, port, tourism, or environmental information.
Brunswick is incorporated, while St. Simons Island, Jekyll Island, Sea Island, and other communities have different administrative arrangements. Because the finished source image was not supplied, the article does not claim that every island and community name appears on every map.
Brunswick and a Deep-Water Port
Brunswick became the county seat in 1797 and developed around a natural harbor formed by the Brunswick, East, and Turtle rivers. Cotton, lumber, naval stores, and other products once moved through the port, linking inland Georgia with Atlantic shipping.
The Port of Brunswick is now a major U.S. gateway for automobiles and machinery. The city also contains county government, the College of Coastal Georgia, historic squares, residential neighborhoods, and seafood-related businesses.
St. Simons Island and Colonial History
St. Simons Island is the county’s largest population center outside Brunswick. Residential areas, beaches, shops, golf courses, and visitor services share the island with Fort Frederica National Monument and the St. Simons Lighthouse.
Fort Frederica preserves an eighteenth-century British settlement and military post. Nearby battle sites record the conflict that helped secure Georgia against Spanish expansion from Florida.
Jekyll Island, Sea Island, and Different Visitor Landscapes
Jekyll Island is state-owned and managed with limits on development. Its beaches, historic club district, bicycle routes, campgrounds, and Georgia Sea Turtle Center combine public recreation with coastal conservation.
Sea Island has a more private resort and residential identity, while Little St. Simons Island emphasizes protected habitat and limited access. These islands share the same county but differ greatly in land management and visitor use.
Marshes, Rivers, and Coastal Access
Salt marshes occupy broad areas between the mainland and barrier islands. Tidal creeks, estuaries, and rivers provide nursery habitat for fish, shrimp, crabs, birds, and other wildlife central to coastal ecology and the local seafood tradition.
The Sidney Lanier Bridge crosses the Brunswick River and carries traffic toward Jekyll Island and the southern county. Its name refers to the poet who wrote “The Marshes of Glynn,” one of the best-known literary descriptions of the Georgia coast.
