Orlando Science Center will host OSC After Dark, an adults-only Halloween party, from 8 to 11 p.m. on Saturday, Oct. 31, 2026.
Presented by the Young Professionals for OSC, the 21-and-older event will give guests after-hours access to the museum, which will be decorated for Halloween.

Admission includes an open bar with cocktails, beer, wine and nonalcoholic beverages; food will be available for purchase from local food partners.
The evening’s programming includes a Halloween-themed laser light show, costume contest, karaoke, trivia hosted by Curtis Earth, a vendor market and a pumpkin-picking challenge. Guests can also visit the observatory, explore the Science Center’s exhibits in a kid-free setting and dance in DinoDigs during the Monster Mash.
Costumes are encouraged. Face coverings cannot obstruct vision and must be removable for identification checks if requested; weapons are not permitted. Proceeds will support Orlando Science Center’s science-learning mission.
