Happiness (Korean: 해피니스; RR: Haepiniseu) is a 2021 South Korean television series produced by Studio Dragon and starring Han Hyo-joo, Park Hyung-sik and Jo Woo-jin. It is an apocalyptic thriller that takes place in a time where infectious diseases have become the new normal. It aired on tvN every Friday and Saturday at 22:40 (KST) from November 5 to December 11, 2021. It is also available for streaming on Viki, Viu, Netflix, Amazon Prime Video, Max, and iQIYI in selected territories.

While achieving respectable but modest ratings during its original run, Happiness became a sleeper hit upon its global release on streaming platforms in April 2022. Thanks to good word of mouth, appreciation for the chemistry between the two leads and execution of zombie genre, it rose to number six on the Most Popular TV Shows ranking on Netflix worldwide.

Due to the success of the series, Han Hyo-joo was nominated for Best Leading Actress and the Popular Star Award at the 2022 Blue Dragon Series Awards, of which she won the latter.
