Yearsley is a small village and civil parish in the district of Hambleton in North Yorkshire, England. The population of the civil parish was less than 100 at the 2011 Census. Details are included in the civil parish of Brandsby-cum-Stearsby. It is situated between the market towns of Easingwold and Helmsley.

The entire parish of Yearsley is within the Howardian Hills Area of Outstanding Natural Beauty. It was, and remains, a predominantly agricultural village with significant forestry on the moors to the north of the village.

The name 'Yearsley' is recorded in the Domesday Book as 'Eureslage' and then, in the Pipe Rolls of 1176, as 'Euereslai'. The origins of the name, however, are probably Anglo-Saxon, from a word meaning Boars' Wood. Following the Norman invasion, the lands of Yearsley fell into the hands of a Norman knight, Roger de Mowbray, who, by 1160, passed the estates to another Norman nobleman, Thomas Colville (from Colleville-sur-Mer on the Normandy coast). The heirs of Thomas Colville (also all called Thomas) owned the lands of Yearsley until 1398 when the next heir, William Colville, took the step of calling himself by the name of his English, rather than erstwhile Norman lands, and became William Yearsley. The manorial estates of Yearsley passed to Sir William Yearsley (who was Clerk of the Wardrobe to Henry VI) and, in 1482, to a third heir, Thomas Yearsley, who died without male heirs in 1497. Through marriage, the estates of Yearsley then passed (by Thomas Yearsley's daughter, Thomasin) to William Wildon of Fryton.

Yearsley is the site of a number of barrows and other early earthworks. Yearsley was also the site of the pottery of William Wedgewood, a relation of the famous Staffordshire Wedgwood family of potters. The village was part of the Newburgh Priory estate of the Wombwell family until 1944.

Yearsley was part of the parish of Coxwold until it became an ecclesiastical parish in 1855 (although this was not sustained) and a civil parish in 1866.

The Pond Head reservoir between Yearsley and Oulston is fed from the nearby source of the River Foss.

The local church was built in 1839 as a chapel of ease to the Church of St Michael in Coxwold. It is a Grade II listed building.
