Arthur William FitzRoy Somerset (20 September 1855 – 8 January 1937) was an English first-class cricketer.
Though hailing from Chatham, Kent, Somerset moved to Castle Goring, a country house now in the town of Worthing in Sussex, and former home of Sir Bysshe Shelley, grandfather of the poet Percy Bysshe Shelley. Somerset played 48 games for Sussex and London County between 1891 and 1906.
As a right-handed batsman and occasional right-arm fast bowler, he scored 1,221 runs at a batting average of 20.01 and took two wickets at 26.50 runs per wicket.
