Morton-on-Swale is a large village and civil parish in North Yorkshire, England. It lies on the A684 road about 4 miles (6.4 km) west of the county town of Northallerton. It is less than 1 mile (1.6 km) to the village of Ainderby Steeple. As the name suggests it lies on the River Swale.

The toponymy of the village is derived from the Old English word mōr for Moor and the word tun for farm, with the addition of the geographical reference to the nearby river, giving Moor farm on the River Swale.

The village is mentioned twice in the Domesday Book as Moretun. At the time of the Norman invasion, the lands were part of the manor of Kirkby Fleetham held by Gospatric, son of Arnketil, with some lands held by Grim. Afterwards the descent of the manor followed that of Ainderby Steeple.

The village is in the Richmond UK Parliament constituency and the Swale electoral division of North Yorkshire County Council. Morton-on-Swale electoral ward stretches north to Danby Wiske and had a population at the 2011 Census of 1,761. From 1974 until 2023 it was in the Hambleton District.

The parish boundary is formed by the River Swale on the west and River Wiske on the east and south. The northern boundary runs just south of Thrintoft. The neighbouring parishes are Ainderby Steeple, Thrintoft, Scruton, Leeming, Gatenby, Maunby, Newby Wiske and Warlaby. The village straddles the A684 road between Northallerton and the A1M motorway. The villages of Ainderby Steeple and Thrintoft are within. The highest point in the village is 131 feet (40 m) at the recreation ground.

In September 2000, the Environment Agency installed a river level monitoring station to measure the water levels in the Swale. The range is between 0.13 metres (0.43 ft) and 5.8 metres (19 ft). The highest recorded level at this point was 6.47 metres (21.2 ft) on 6 September 2008.

The Wensleydale Railway Association extended its line, that runs from Redmire and Leeming Bar, to run just to the north of the village with a temporary station at Northallerton West and plans to go as far as the East Coast Main Line. This has meant the construction of two level crossings in the village.
