Locust Grove, also known as the Old Jacob Brubaker House is a historic house in rural Page County, Virginia. It is located about 7 miles (11 km) southeast of Luray, at 6601 Ida Road. It is set on the south side of the road, just west of Chub Run. It is a 2-1/2 story brick house, with a gable roof, and a single-story side ell. Built about 1830, it is a good local example of Federal period style, retaining original interior floors, woodwork, and fireplace mantels.
