Gathering of the Ghouls Brings Mesa’s Main Horror Convention Weekend to the Convention Center
- The fourth annual horror and Halloween celebration returns to Mesa Convention Center on Saturday, Aug. 22, with ticketed admission, celebrity guests, cosplay, and more than 100 horror vendors.
Mesa’s horror fans have a big weekend of spooky fun on the horizon as the 4th Annual Gathering of the Ghouls returns to the Mesa Convention Center on Saturday, Aug. 22, 2026. The event is being billed on the official Gathering of the Ghouls website as a two-day Halloween and horror convention, but Saturday’s programming appears to be the week’s biggest convention-style draw, with single-day admission listed on the event’s ticket page.
Running from 11 a.m. to 7 p.m. on Saturday, the event is designed for fans of horror, Halloween, haunted houses, cosplay, and spooky creativity. The convention’s Eventbrite listing says attendees can expect 100 horror vendors, celebrity guests, a haunted house, cosplay contest, and photo ops, while the official site notes the event is a staple for horror fans looking to kick off the season early.

The show is also being promoted on the event’s Instagram account and Facebook page, where organizers highlight the convention’s mix of horror fandom, Halloween spirit, and community energy. Ticket info currently includes single-day admission for Saturday, with the official site also listing multi-day access for those planning to make a full weekend of it.
For fans looking for the most convention-like experience of the week, Gathering of the Ghouls is the obvious centerpiece. Between the vendor floor, special guests, and a full slate of horror-friendly programming, it offers a more immersive option than a typical screening, haunt, or pop-up market. For Mesa, it’s another sign that horror culture has a solid late-summer home in the Valley.
