60 free Star Trek: the Original Series trivia questions with answers — entertainment quiz, new questions added Aug 2026.
Before the films, the spin-offs and the reboots there were 79 episodes of Star Trek on NBC between 1966 and 1969, cancelled after three seasons and then turned into a phenomenon by syndication. This Star Trek original series trivia quiz stays inside those episodes and their making: the rejected pilot with Captain Pike, how Spock survived the network's objections, why Chekov arrived in season two, the tribbles, Khan, the Gorn, the salt vampire, the interracial kiss in Plato's Stepchildren, the fan letter campaign that saved season three, and the composers, designers and guest stars behind the show. The 60 questions run from easy (who plays Dr. McCoy?) to expert (which prop artist designed the communicator?), so it works for casual fans and for people who can quote stardates. Every answer has been checked against documented production and broadcast records rather than fan wikis, so the answer key is one you can trust at a pub quiz.
