Ayr Mount is a Federal style plantation house located east of Hillsborough, in Orange County, North Carolina, the United States of America. In 1799, William Kirkland (born in Ayr, Scotland) bought 500 acres (2.0 km2) east of Hillsborough. Circa 1815, he had a home built for himself, his wife, Margaret, and their children, a brick dwelling with a two-story, three-bay main block flanked by one-story, two-bay wings. A full-width front porch, added about 1894, was removed sometime after 1971 and replaced with a facsimile of the original porch.
