OSC After Dark 2026 brings a 21-and-over Halloween party to Orlando Science Center on Saturday, October 31, 2026, from 8:00 p.m. to 11:00 p.m. Hosted by the Young Professionals for OSC, the night turns the decorated museum into a costume party packed with laser shows, karaoke, trivia, a costume contest and an open bar.

What You Need to Know

Since everyone is checked for ID at the door, bring a valid photo ID and plan a costume you can easily take off or lift a mask from. The open bar is covered by your ticket, but the food isn’t, so set aside a little extra if you plan to snack. With the laser show, karaoke, trivia, the observatory and a dance floor all going at once, it helps to look over the lineup ahead of time and pick your must-dos.

Adults-only nights are a familiar format at the museum. We’ve covered past events like Science Night Live and the Science on Tap craft beer fundraiser, and OSC After Dark adds a Halloween twist to that idea. Sponsors for this year’s party include HiFive Ad Agency, Koffee Sutra, Lowndes, Massey Services, Inc., Orlando Magic, Shutts Attorneys at Law and Verizon.
