Osterhout Log Cabin, Historical log cabin in Guildwood Park, Scarborough, Canada

The Osterhout Log Cabin is a log building in Guild Park and Gardens, Guildwood, Scarborough, Toronto, set along the Scarborough Bluffs. It is one of the oldest surviving buildings in Scarborough, documented in local records by the mid-19th century, and is a designated heritage building.

The cabin was constructed after 1845, representing a later phase of settlement in the area. The land had been originally granted in the early 1800s to a United Empire Loyalist who fought in the American Revolution.

The cabin reflects how early settlers constructed their homes and organized daily life in the new landscape. Visitors can see the practical choices these people made in building techniques and space use that suited their circumstances.

The cabin sits within a public park that features other historic buildings and is straightforward to explore. The location offers plenty of room to walk around and spend time, particularly when the weather cooperates.

Local lore holds that Augustus Jones and his survey team built the cabin around 1795 as shelter while charting the Scarborough lakeshore, but Jones never mentioned building it and recorded that his team lived in tents. In 1996 University of Toronto archaeologist Marti Latta excavated the site and concluded James Humphreys, who bought the land in 1845, was the likeliest builder.
