Sir William Batten (c.1601–1667) was an English naval officer and administrator whose career spanned the English Civil Wars and the Stuart Restoration. Initially a Parliamentarian commander, he switched allegiance to the Royalists in 1648, later returning to the navy under the Restoration.
His time as Surveyor of the Navy overlapped with Samuel Pepys, whose diary criticizes his administrative shortcomings, while historical records emphasize his strategic contributions to achieving naval supremacy. From the Encyclopædia Britannica to Pepys’s personal accounts, Batten appears as a figure of disputed legacy—both a practical naval leader and a man caught in political conflict, embodying the turbulent period he experienced.
