The Waterford Greenway, also known locally as the Déise Greenway, is a route on a former railway track in County Waterford, Ireland, used for cycling and hiking.

It opened in March 2017, on what was originally the Mallow/Waterford railway line, and forms part of EuroVelo 1 route.

[3] The Waterford Greenway features 11 bridges, three viaducts and a 400-metre tunnel and runs between the city of Waterford, Mount Congreve, Kilmeaden, Kilmacthomas, and Dungarvan, and passes along part of the Copper Coast.

[4] In July 2020, funding was announced for a feasibility study to investigate extending the greenway towards Mallow along the former Waterford-Mallow railway line.

[5] This initial feasibility study is due to examine the possibility of an 38.5 kilometre extension between Dungarvan and Ballyduff near the border with County Cork.
