John Baptista Verbruggen, d. 1708, was an English actor working in London. Verbruggen is first mentioned as a member of the United Company in a Lord Chamberlain's warrant in 1688. His name does not appear in any cast lists until October 1690. The Biographical Dictionary of Actors contains an inconclusive discussion of the claim in Davies' Dramatic Miscellanies (1784) that Verbruggen was identical to the actor referred to in 1680s and 90s cast lists as "Mr. Alexander", supposedly an alias based on the part of Alexander the Great in John Dryden's Rival Queens. The evidence is confusing, and there is no independent support for Davies' anecdote, written down a century later. Verbruggen had never played the part of Alexander the Great and was not to do so until January 1703.
