100 free Blue Bloods trivia questions with answers — entertainment quiz, new questions added Oct 2026.
This Blue Bloods trivia quiz covers all 14 seasons and 293 episodes of the CBS police drama that ran from September 2010 to December 2024, plus the Danny Reagan spin-off Boston Blue. It asks about the Reagan family tree — Commissioner Frank, retired Commissioner Henry, Detective Danny, Assistant DA Erin, Sergeant Jamie, the murdered Joe and the grandson nobody knew about — and about the partners who shared their working lives: Baez, Curatola, Eddie Janko, Garrett Moore, Abigail Baker, Sid Gormley and Anthony Abetemarco. There are questions on the cast (Tom Selleck, Donnie Wahlberg, Bridget Moynahan, Will Estes, Len Cariou, Vanessa Ray, Sami Gayle) and their earlier lives in Magnum P.I., New Kids on the Block, Sweeney Todd and Pretty Little Liars, on the Blue Templar storyline that drove season one, on the Bay Ridge house and the Brooklyn soundstages, on the ratings records, the pay cut that bought the final season, and Danny's move to the Boston Police Department. Some are easy for anyone who has watched a Sunday dinner scene; others are for people who never missed a Friday night. Every answer has been checked against Wikipedia and each question carries a citation to the page it came from.
