There are haunt conventions, and then there’s the Ohio Haunters Convention. Most industry events are held in convention centers—functional, forgettable spaces that exist to move foot traffic past vendor booths. The Ohio Haunters Convention does something fundamentally different: it puts you inside the Ohio State Reformatory, a 136-year-old Gothic-revival prison campus in Mansfield, Ohio, that has served as both a Hollywood filming location and one of the Midwest’s most celebrated haunted attractions. You’re not just attending a convention. You’re attending a haunt convention *inside* a haunt.

For operators, this matters. Walking vendor aisles in a space this atmospheric shifts how you think about your own haunt design. For enthusiasts and scare actors, it’s simply one of the most memorable weekend experiences the industry offers.

The Venue: Ohio State Reformatory — History and Haunt Legacy

The Ohio State Reformatory opened in 1896 and operated as a prison until 1990. Its Gothic and Romanesque architecture—soaring cell blocks, vaulted ceilings, ironwork, and stone corridors—has made it one of the most-photographed historic sites in Ohio. Most people first encounter it through cinema: the Reformatory served as Shawshank State Penitentiary in Frank Darabont’s 1994 adaptation of Stephen King’s Rita Hayworth and Shawshank Redemption.

Since closing as a correctional facility, the Reformatory has been operated by the Mansfield Reformatory Preservation Society. Its primary Halloween event, Blood Prison, runs each October and consistently ranks among the top haunted attractions in Ohio. The convention makes use of the same Blood Prison venue space, meaning attendees are literally walking the floors of an operational professional haunt while browsing prop vendors and sitting in industry seminars.

Event Details at a Glance

The 2026 Ohio Haunters Association Convention runs May 15–17, 2026 at the Ohio State Reformatory, 100 Reformatory Road, Mansfield, OH 44905. The event is open to OHA members and non-member industry professionals, haunt owners, scare actors, prop builders, vendors, and horror enthusiasts. Attendees must be 18 or older. Free parking is available in the Reformatory lot adjacent to the Blood Prison entrance, with accessible spaces clearly marked.

Ticket information and current registration pricing are available through the Ohio Haunters Association at ohiohaunters.com. Given the venue’s size and the event’s growing national profile, early registration is strongly recommended.

What’s on the Show Floor

The vendor hall brings together prop manufacturers, costume suppliers, lighting and audio vendors, special effects companies, and regional haunt services under one roof. For operators, this is a concentrated buying opportunity: you can physically examine animatronics, test lighting rigs, and negotiate directly with vendors—no shipping uncertainty, no guessing from a catalog photo.

Expect representation from major prop houses alongside regional artisan builders who create custom pieces unavailable through mainstream retail. The convention’s Ohio-centric attendee base also makes it an excellent venue for networking with regional actors, makeup artists, and contractors who are actively looking for seasonal work.

Programming and Industry Seminars

The Ohio Haunters Association structures the convention around education as much as commerce. Seminar programming covers topics including haunt marketing strategies, ticket pricing and revenue optimization, actor management and training, safety protocols, and prop construction workshops. Sessions are presented by working haunt operators and industry specialists—practitioners, not theorists.

For newer haunt owners and operators building their first professional attraction, the seminar track alone is worth the registration fee. The condensed format—three days of sessions delivered by experienced operators—provides the kind of peer knowledge transfer that would take years to accumulate through independent operation.

Who Should Attend Ohio Haunters Convention 2026

Haunt Operators: The vendor floor and seminar track are purpose-built for you. Come with a buying list and specific operational questions. The venue atmosphere also provides genuine design inspiration that a conference center never could.

Scare Actors and Performers: Networking with Ohio-area haunts in person is the single most efficient way to secure seasonal bookings. Bring a portfolio, your availability calendar, and business cards.

Prop Builders and Designers: The vendor floor is a marketplace for your work and a research trip for your craft. Many custom prop commissions originate from conversations started at events like this.

Haunt Enthusiasts: If you love haunted attractions and want a behind-the-scenes perspective on how they’re built and operated, this convention offers a level of access unavailable anywhere else—inside an active professional haunt venue.

Getting There: Mansfield, Ohio Travel Tips

Mansfield sits roughly 75 miles southwest of Cleveland and 75 miles northeast of Columbus, making it accessible from both major metro areas in under 90 minutes by car. The Ohio State Reformatory is at 100 Reformatory Road—GPS navigation is reliable. Several hotel options are clustered within 5–10 minutes of the venue along Route 30 and in downtown Mansfield. Book early: haunt conventions tend to block-book local hotel inventory faster than attendees expect.

For those flying in, Cleveland Hopkins International (CLE) and John Glenn Columbus International (CMH) are the closest major airports, both approximately 80 miles from Mansfield. Car rental at either airport is the most practical option.
