The Thomas Grant Harbison House is a historic house at 2930 Walhalla Road, just outside Highlands, North Carolina. The two-story wood-frame house was built in 1921 for the botanist Thomas Grant Harbison (1862-1936), who was responsible for some of the surviving plantings, including a stand of the endangered Torreya taxifolia, on the extant property. The south (street-facing) facade is five bays across, with a two-story porch sheltering the center three bays and the entrance. The north-facing facade has a similar porch that is only a single story. The house remained in the Harbison family until 1985.

The house was listed on the National Register of Historic Places in 2008.
