The Northumberland County Historical Society is a Pennsylvania nonprofit organization, which was chartered on October 26, 1925 and incorporated on May 21, 1998. Its leaders, members and volunteers are dedicated to the collection, preservation and exhibition of artifacts, documents, photographs, and other items which tell the story of Northumberland County, Pennsylvania and its people.

Headquartered at the Hunter House Museum at historic Fort Augusta in Pennsylvania's upper Susquehanna Valley, the Historical Society is also home to the Charlotte Darrah Walter Genealogical Library, and presents programs on topics of interest to historians, genealogists and members of the general public at various times during each calendar year. The facilities, which are open from March through December (but closed during the winter months), are physically located at 1150 North Front Street in Sunbury, Pennsylvania.

The Charlotte Darrah Walter Genealogical Library houses materials from the time of the region's earliest settlers to the present, including biographical sketches and books published about Northumberland County families; birth, marriage, death, and cemetery records; baptismal, confirmation, burial, and other church records; historic newspapers and vintage photographs; and land deeds, tax rolls, wills, and other county records, etc.

During the early 1930s, the Commonwealth of Pennsylvania took steps to preserve historic Fort Augusta and its surrounding lands through a series of preservation initiatives. Initially purchasing, in 1930, a tract of land where the original powder magazine and well of Fort Augusta were located, state officials then also purchased, in 1931, the historic Hunter House, which had been completed in 1852 by Captain Samuel Hunter, a grandson of Fort Augusta's commandant, Colonel Sam Hunter. Those properties were then acquired by the Northumberland County Historical Society, Inc. from the Pennsylvania Historical and Museum Commission in 2004.

According to historian Margaret Murray Thorell, Ph.D., when the Hunter House became the headquarters for the Northumberland County Historical Society in 1987, "an extensive renovation restored the brick house [Hunter House] to its original 1848 appearance and added meeting space at the rear of the structure."

The holdings at Hunter House Museum include that original powder magazine from Fort Augusta, as well as Native American and Moravian blacksmith artifacts, the uniform and drum of John Boulton Young, a drummer boy who died at the age of 13 while serving with the 47th Pennsylvania Infantry Regiment during the U.S. Civil War, and other items of historic interest which were uncovered during archaeological digs in 1937-1938, 1978-1979, and 1981.

A model of Fort Augusta was built on the front lawn of the Hunter House Museum and dedicated in 2013. It is roughly one-sixth of the size of the original fort, which was built in 1756 to protect settlers during the French and Indian War.

The society has historically sponsored educational outreach initiatives through an annual series of meetings and other special events. Topics addressed have included:

• The debunking of local and state history myths;
• Displays of period-era uniforms, vehicles, and weapons from the American Civil War and World War II; and
• The impact of the 1918 Spanish influenza on the coal industry in Northumberland County (March 16, 2018)

In addition to preservation of the Hunter House (see above), society members also collaborate with other organizations to advocate for and ensure the preservation of historic structures across the county. In 2015, society joined with the Old Towne Neighborhood Council in fighting to save the Northumberland County Prison (Pennsylvania), a 139-year-old castle-like structure which had recently been devastated by a major fire.

Over the years, the Northumberland County Historical Society has partnered with historians and genealogists to produce books, pamphlets and other educational materials, including:
