County Route 115 (CR 115) is a northwest–southeast county highway located mostly within the town of Caroline in Tompkins County, New York, in the United States. It extends for 12.8 miles (20.6 km) from the Tioga County line south of the hamlet of Speedsville to an intersection with New York State Route 79 (NY 79) just north of the Caroline town line in the town of Dryden. The highway continues into Tioga County as CR 33. The portion of CR 115 north of the hamlet of Guide Board Corners was originally designated as New York State Route 330 and maintained by the state of New York. NY 330 existed from the early 1930s to 1980, when ownership and maintenance of the highway was transferred to Tompkins County.

CR 115 begins at the Tioga County line in the town of Caroline, where it connects to Tioga County's CR 33. The county highway passes a mountain to the west and the Owego River's west branch to the east as it heads northward. It crosses Boyer Creek as 76 Road and enters the hamlet of Speedsville, a small community located on top of a mountain. Here, CR 115 turns to the northwest to run along the base of a valley surrounding Boyer Creek. The creek reaches its source at an intersection with Yaple Road; however, CR 115 continues northwestward to serve the hamlet of Caroline Center.
