John Gibbs Gilbert (February 27, 1810 – June 17, 1889) was an American stage actor.
His original aim was to be a tragedian, but while on a tour through the South and West, the success of his Sir Anthony Absolute, Master Walter, etc., convinced him that his true bent was for "old men" parts, and he soon became the leading American actor in that line of comedy.
The Tremont was managed then by Thomas Barry, who died on February 11, 1876, full of years and honors.
The versatility of his talents and the variety of his efforts at that time are denoted by the list of parts which he acted during the first season with Barry.
This includes Master Walter, Isaac of York, Sir Peter Teazle, Pizarro, Iago, Sir Edward Mortimer, Admiral Kingston, Lieutenant Worthington, Sir Robert Bramble, Polonius, Uncle John, Tom Noddy, Macduff, Mr. Dornton, Squeers, King Henry the Sixth, Adam, Malec, Kent and Rolanio.
