Cuckoo is a small unincorporated community in Louisa County, Virginia, United States. It is located about eight miles southeast of Louisa, roughly between Charlottesville and Richmond. The Cuckoo Tavern stood nearby, which in 1781 was the beginning of Jack Jouett's ride to warn the Colonists of the arrival of Banastre Tarleton's British cavalry (similar to Paul Revere's Ride). There was also a large house named Cuckoo built in 1819 for Henry Pendleton on the former property of William Overton Callis. A historical marker is at the spot.
