Lleweni Hall (Welsh: Plas Lleweni; sometimes also referred to as Llewenny Palace) was a stately home in Denbighshire, northeast Wales, around 2 miles (3.2 km) north-east of Denbigh on the banks of the River Clwyd. It was the principal seat of the Salusbury family and their descendants from 1289 until 1748, and the present territorial designation of the most senior branch of the family.
