Giovanni Battista Boazio (fl. 1588 – 1606) was an Italian draftsman and cartographer. He mapped Sir Francis Drake's voyage to the West Indies and America.
He spent a long period working in England, and made a map of Ireland that was then used in the Theatrum Orbis Terrarum. He was sponsored by Robert Devereux, 2nd Earl of Essex to draw a map illustrating the Capture of Cadiz, which was engraved by Thomas Cockson.[1]
