Indiana Repertory Theatre, frequently abbreviated IRT, is a professional regional theatre in Indianapolis, Indiana that began as a genuine repertory theatre with its casts performing in multiple shows at once. It has subsequently become a regional theatre and a member of the League of Resident Theatres. A standard season typically consists of nine or ten plays on two different stages (with at least two selected especially although not exclusively for student audiences, one of which is often a Shakespeare play) and the bulk of its season (including a holiday show, usually Charles Dickens's "A Christmas Carol") performed on the "OneAmerica Stage".
