The Gerrit Smith Estate is a historic residential estate at Oxbow Road and Peterboro Road in Peterboro, New York. It was home to Gerrit Smith (1797-1874), a 19th-century social reformer, abolitionist, and presidential candidate, and his wife, Ann Carroll Fitzhugh. Smith established an early temperance hotel on his estate, and it was a widely known stop for escaped slaves on the Underground Railroad. The surviving elements of the estate were declared a National Historic Landmark in 2001. The estate is now managed by a nonprofit organization, and is open for tours from June to August.
