Harlequin Theatre, the oldest collegiate theatre organization in Arkansas, presents major productions in the fall and spring. Students from all disciplines are welcome to participate as actors, technicians, and designers. The completion of the Holloway Theatre in 1991 provided the Harlequin Theatre with a space designed to meet the diversified needs of modern collegiate theatre.
Theatre at Lyon is part of the liberal arts educational process. Students are given opportunities to act, direct, design, and write plays. Every year select students attend and often compete at the Region VI Kennedy Center American College Theatre Festival.
