50 free Phoenix, Arizona trivia questions with answers — geography quiz, new questions added Aug 2026.
Phoenix is the fifth-most populous city in the United States and the biggest state capital by far, a grid of wide streets laid over canals the Hohokam dug two thousand years ago. It was named by an Englishman who saw a city rising from the ruins of an older civilisation, grew on cotton, cattle, citrus, climate and copper, and then exploded after the Second World War once air conditioning made the summers survivable. These 50 questions cover the whole story: Jack Swilling's irrigation company, the 1881 charter signed by John C. Fremont, the dam Theodore Roosevelt dedicated, the 1920 skyscraper, Motorola's arrival, Sandra Day O'Connor and the first female mayor. There are sports questions on the Diamondbacks' 2001 World Series, the Cardinals' move from St. Louis and the Mercury's three WNBA titles, plus geography on the Sonoran Desert, the Salt River, Piestewa Peak and the world's largest municipal park. Easy questions stick to Sky Harbor, Chase Field and the Valley of the Sun; the hardest ask about the first sheriff, the first newspaper and the pope who created the diocese. Every answer is cited to a page we checked, with a short explanation so you learn something even when you miss. Play it solo or print it for an Arizona trivia night.
