Sir John Salusbury was a Welsh knight, politician and poet of the Elizabethan era. He is notable for his opposition to the faction of Robert Devereux, 2nd Earl of Essex, and for his patronage of complex acrostic and allegorical poetry that anticipated the Metaphysical movement.

Lleweni Hall 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.
