Sir Roger Newdigate, 5th Baronet (30 May 1719 – 23 November 1806) was an English politician who sat in the House of Commons between 1742 and 1780.

[1] Newdigate was born in Arbury, Warwickshire, the son of Sir Richard Newdigate, 3rd Baronet (who died in 1727) and inherited the title 5th Baronet and the estates of Arbury and of Harefield in Middlesex on the early death of his brother in 1734.

He is best remembered as the founder of the Newdigate Prize on his death[3] and as a collector of antiques, a number of which he donated to the university.

[4] He lavished attention on the Elizabethan Arbury Hall which he rebuilt over a period of thirty years in splendid Gothic Renaissance style, engaging the services of the architect Henry Couchman.

Arbury Hall and Harefield passed to Francis Parker (1774–1862) of Kirk Hallam, Derbyshire, a distant cousin of the 5th Baronet, who then adopted the additional name of Newdigate.
