Gisippus is an 1842 tragedy by the Irish writer Gerald Griffin.

It premiered at the Theatre Royal, Drury Lane in London on 23 February 1842.

[1] It was staged posthumously as Griffin had died from typhus in 1840, and was likely written before 1838.

The original cast included William Macready as Gisippus, James Robertson Anderson as Titus Quintus Fulvius, Edward Elton as Pheax, George Bennett as Lycias, Charles Selby as Macro and Helena Faucit as Sophronia.

Its opening resembles William Shakespeare's Julius Caesar, but with the setting switched from Rome to Athens.
