Monster-Mania Con is a semi-annual horror film and memorabilia fan convention held in the United States, operating since 2003.

It is focused on guest panels, where attendees of the convention can meet actors, primarily ones who have acted in horror films.

The show's lineup included Doug Bradley, Caroline Munro, Ben Chapman, Veronica Carlson, amongst many others.

[4][5][6] After thirteen years of hosting the convention in Hunt Valley, Maryland, Monster-Mania was forced to relocate due to the closure of the Delta Marriott Hotel.

There are also vendors, film presentations, previews, photo ops, music performances, and Q&As with select guests, along with an auction for Yorkie dogs.
