The Lincoln County Historical Society's collection contains more than 40,000 artifacts focusing on the 1850s to the present. The collection consists primarily of objects made or used on Oregon's central coast, and is the largest collection of such objects. The collection includes: clothing, quilts and other textiles, firearms, tools, furniture, jewelry, china, arts and crafts, musical instruments, Native American objects, and maritime objects.

The Society owns and maintains two historic buildings: the Burrows House Museum and a structure on Newport's historic Bayfront slated to become the Pacific Maritime & Heritage Center.

The Society also houses an extensive archival collection, available in the Research Library.

The Kingfisher
The largest artifact is the CV Tradewinds Kingfisher, a charter boat which was in service from 1941 until it was donated to the Society in 2001. The vessel is listed on the National Register of Historic Places.
