Felliscliffe is a civil parish in North Yorkshire, England, in Nidderdale, Harrogate borough. The population of the civil parish at the 2011 census was 283. The principal settlement in the parish is the village of Kettlesing, and the parish also includes the hamlet of Swincliffe. Felliscliffe was historically a township in the ancient parish of Hampsthwaite in the West Riding of Yorkshire, first mentioned in the Domesday Book as Felgesclif, apparently from an Old Danish personal name Felagh.
The parish is west of Harrogate. It includes part of the US intelligence-gathering base at Menwith Hill. Kettlesing Felliscliffe Community Primary School is in Kettlesing.
The parish served the nearby Fountains Abbey with flax, with monastery paths leading along Tang Beck, a tributary of the River Nidd, still in existence. Traces of Iron Age and Roman settlements have been discovered in the parish, indicating that it has been inhabited continuously for several millennia.
The parish skyline, on the ridge to the south of the A59, is now dominated by the eight 58 m wind turbine towers of the "Knabs Ridge" windfarm.
