A parade, food, crafts and a market will also be on offer.
Santa is coming to a midlands town this weekend to turn on the Christmas lights.
Tullamore is kicking off its festive celebrations today, with the Christmas market opening this afternoon - that will include food, crafts and music.
The festive lights will be switched on this Sunday at 6pm, with Santa himself doing the honours.
As well as that, there'll be a parade featuring his elves, and other evens such as face painting and choir singing.
