Maryland Halloween Events 2021

Are you ready to track down some fun events for Halloween 2021? We have put together one of the largest calendars of Halloween events in the United States for you. It locates holiday activities for all ages – from kid-friendly children’s activities to adult Halloween parties. We don’t have every event yet, but there are plenty of ideas to get you and your family in the mood for Halloween in Maryland.

Last Major Update:

At this point we have checked for 2020 dates on all events. Some websites are still holding off on releasing a date, whereas other websites have not been updated at all for this year. We leave the links up from previous events so you can check yourself if it hasn't updated yet.
All events showing 2020 dates need to be verified to confirm that changes to the schedule were not made by the organizers after publication here, due to COVID-19 (or weather or other conditions). We do not run these events, and would hate for anyone to go out of their way only to find the event had been canceled after releasing a date. Please click through to the event website to confirm! Be safe and have a great fall!
