Sir William Boswell (died 1650) was an English diplomat and politician who sat in the House of Commons in 1624 and 1625.
[2] Boswell subsequently entered the diplomatic service, and was appointed secretary to Sir Dudley Carleton, then ambassador at The Hague.
[4] Charles I ordered Boswell to back Edward Misselden, influential in the Merchant Adventurers, against John Forbes.
[7] When the First English Civil War broke out, Boswell's efforts were directed towards preserving the neutrality of the Dutch.
[8] Sir William was also a man of letters and a scholar, as is shown in his correspondence with John de Laet, which touches upon subjects ranging from Oriental literature and the compilation of an Arab dictionary to Edward VI's treatise 'De Primatu Papae,' and Sir Simon d'Ewes's Saxon vocabulary.
