The Metro Monster Mash takes place in the car park of the Odyssey Arena on 28 October with events for all the family, culminating in the traditional fireworks extravaganza.
Entertainment will be provided by the magical talent show duo who wowed BGT judges with their Harry Potter trick, and performance of The World's Most Difficult Card Trick.
They will be supported by local band Silhouette, with fun activities including theatre, wacky workshops, face-painting and breath-taking fire shows also planned for the day.
Belfast Mayor Gavin Robinson said: "The Metro Monster Mash is one of the highlights of our events calendar and will offer a fantastic feast for the senses and for all ages - with all this spooky fun for free.
"I'm delighted that we have got a fantastic line-up on stage this year with international magicians` Brynolf and Ljung and local band Silhouette performing and keeping the crowds entertained."
The celebrations start at 2pm on Sunday 28 October.
