Newby Hall is a country house beside the River Ure in the parish of Skelton-on-Ure in North Yorkshire, England. It is 3 miles south-east of Ripon and 6 miles south of Topcliffe Castle, by which the manor of Newby was originally held. A Grade I listed building, the hall contains a collection of furniture and paintings and is surrounded by extensive gardens. Newby Hall is open to the public.
In 1973, a miniature railway was constructed; it was enlarged in 1985. Running along the bank of the river, a train is pulled by a Battison-built 1/5-scale model of the Royal Scot (6100) on Sundays and bank holidays.
