Buena Vista is an unincorporated community in Green Township, Fayette County, Ohio, United States. It is located at the intersection of Greenfield-Sabina Road (Fayette County Highway 5) and Stafford Road (Fayette County Highway 3), about 5 miles south of Washington Court House.[1] Rattlesnake Creek flows near the town site.[2]
Buena Vista had its start in the 1830s.[3] Buena Vista was formerly called Moons, after William Moon, an early settler.[4] The present name is said to be a transfer from Buena Vista, Virginia.[5]
A post office called Moon was established in 1833, and remained in operation until 1907.[6]
