Sir Charles Hobby (1665–1715) was a Boston merchant and militia colonel, commanding a provincial regiment during the siege of Port Royal 1710, and serving as its acting governor in 1711.

[2] Hobby's wealth and connections made him a captain of the Ancient and Honorable Artillery Company and a colonel of a regiment of Massachusetts militia.

[3] Anglican in religion, Hobby was a vestryman of the King's Chapel, together with Governor Joseph Dudley and Captain Cyprian Southack.

Returning to Boston the same year, Hobby continued his mercantile activities, investing in Nova Scotia property and trade.

He tried to wrest the governorship of that colony from Vetch; again proceeding to London, and yet again making peace with his antagonist, and was recommended as lieutenant governor.
