Richard Griffin, 2nd Baron Braybrooke (3 July 1750 – 28 February 1825) was an English politician and peer. He was known as Richard Aldworth-Neville or Richard Aldworth Griffin-Neville to 1797.
The only son and heir of Richard Neville Aldworth Neville, he was born on 3 July 1750 in Duke Street, Westminster. He matriculated at Merton College, Oxford, on 20 June 1768, was created M.A. 4 July 1771, D.C.L. 3 July 1810, and was incorporated LL.D. of Cambridge in 1819.
Neville was Member of Parliament for Grampound from 10 October 1774 till the dissolution in 1780, and for Buckingham in the next parliament till his appointment as agent to the regiment of Buckinghamshire militia in February 1782. On the 21st of the same month he was returned for Reading, and was re-elected there for the three succeeding parliaments (1784, 1790, 1796).
On the death, in May 1797, of his father's maternal uncle John Griffin, 4th Baron Howard de Walden, by whom he had been adopted as heir, Griffin-Neville succeeded to the Braybrooke barony. He assumed the additional surname and arms of Griffin, and came into possession of the Audley End estate until the death in 1802 of Dr. Parker, son-in-law of the late Baron, who had a life interest in it. Braybrooke increased the property by the purchase of neighbouring manors and farms from the Earls of Bristol and Suffolk, and other acquisitions. He became Lord Lieutenant of Essex and custos rotulorum of the county immediately after his accession to the peerage (19 January 1798), and was also vice-admiral of Essex, recorder of Saffron Walden, high steward of Wokingham, hereditary visitor of Magdalene College, Cambridge, and provost-marshal of Jamaica.
