Baron Alvanley, of Alvanley in the County Palatine of Chester, was a title in the Peerage of the United Kingdom. It was created on 22 May 1801 for Sir Richard Arden, the Chief Justice of the Common Pleas and former Master of the Rolls.[1][2] The title became extinct on the death of his second son, the third Baron (who had succeeded his elder brother), in 1857.
