Rothschild House, Heritage residence in Port Townsend, United States.

The Rothschild House is a two-story 1868 house built by D.C.H. Rothschild in Port Townsend, Washington. It is run by the Jefferson County Historical Society as a historic house museum, with period furnishings and artifacts from the late 1800s. It was listed on the National Register of Historic Places in 1970 and is part of the Port Townsend Historic District, a National Historic Landmark since 1977.

A Bavarian merchant named David Charles Henry Rothschild built the house in 1868 after establishing his general merchandise business in town. The structure later became an important center for regional shipping trade.

The house shows how prosperous merchants lived and worked in the 1800s, with rooms that still tell the story of regional trade. The local historical society uses the space to demonstrate how family and business were intertwined under one roof.

The house can be explored with knowledgeable guides who explain life and business during the 1800s. There are interior rooms and a garden to see, and comfortable shoes and time to look around are helpful.

D.C.H. Rothschild was nicknamed "The Baron" after the famous Rothschild banking family, though he was a merchant from Sulzbach am Main in Bavaria. His son Henry and partner William J. Jones turned the family business into Jones Stevedoring, still operating at the Port of Seattle.
