Jonathan Bailey House, Historic Quaker house in Whittier, United States.

The Jonathan Bailey House is located on Camilla Street and features original redwood construction with period furnishings spanning from 1865 to 1904. The home preserves the living spaces and personal environment of a family central to Whittier's founding and growth.

The house was built around 1868–1869 by Jacob Gerkens and was later known as "The Old Ranch House". In 1887 it was occupied by the Quakers Jonathan and Rebecca Bailey, who had moved from Ohio at age 68. It is the oldest remaining building in Whittier and was added to the National Register of Historic Places in 1977.

The first Quaker meetings in the area were held on the front porch of the Bailey House, where Jonathan and Rebecca Bailey, who arrived in 1887 at ages around 68, gathered neighbours for worship. The house was formerly called "The Old Ranch House".

The Jonathan Bailey House is maintained by the City of Whittier Park Department with help from volunteers and run as a museum by the Whittier Historical Society. It sits in Whittier, California, and was listed on the National Register of Historic Places in 1977.

The home preserves personal items belonging to the Bailey family, including Jonathan's rocking chair, walking cane, and Rebecca's original herb garden. These everyday objects offer visitors a direct connection to how the family actually lived.
