HQ may refer to any of the following:
1. Short for high-quality, HQ describes the quality of a video, sound, print, or picture that is clear or easy to read.
2. HQ was the name of a mobile trivia game released on August 26, 2017, by the same people who released Vine. In the original HQ Trivia game, players had 10 seconds to answer a multiple-choice question and competed against other players from around the world. If successful at answering questions correctly, participants would win real-life cash prizes. The company would later release other games, but none would become as popular as HQ Trivia. On February 14, 2020, the company sent a memo to staff indicating the company would cease operations.
3. HQ is an abbreviation of headquarters. A business headquarters is the location where most of its operations are handled. For example, Computer Hope is headquartered in Utah.
