Sweet Home (Korean: 스위트홈) is a 2020 South Korean apocalyptic horror television series starring Song Kang, Lee Jin-wook, and Lee Si-young. It is based on the Naver webtoon of the same name by Kim Carnby and Hwang Young-chan, which recorded over 2.1 billion net views.

The first season was released on Netflix on December 18, 2020. The second season was released on December 1, 2023. The third and final season was released on July 19, 2024.

After an unexpected tragedy kills his entire family and leaves him as the only survivor, Cha Hyun-su leaves his family home and relocates into the run down apartment complex known as Green Home. One night, horrific monsters begin appearing and ravage the city. Hyun-su and some of his fellow residents band together within the confines of the complex and must fight for their survival against the new, preternatural threat, while others from the apartment turn into monsters based on the things they desire. Hyun-su starts having monster symptoms and develops the ability to turn into a winged monster whenever he desires.

The survivors of Green Home venture out into the ruined world beyond its walls. Meanwhile, governmental bodies and scientific institutions continue in their efforts to study the monsters, hoping to find a cure.

The survivors continue to face new threats and challenges as they explore deeper into the characters' backgrounds and the origins of the monsters. Cha Hyun-su grapples with his monstrous transformation abilities, playing a pivotal role in defending the survivors and uncovering the mysteries behind the monstrous outbreaks. New and more dangerous monster types are introduced, including human-like creatures emerging from cocoons. Yi-kyung's child, possessing special powers, becomes a significant part of the story. Lee Eun-hyuk returns as a neohuman, forming an alliance with Hyun-su. Efforts by governmental and scientific bodies to understand and possibly cure the monstrous transformations continue, adding another layer of intrigue and hope for the characters.

Director Lee Eung-bok "roughly" knew the ending of the Line Webtoon on which the series is based before the webtoon's finale in July 2020, though he decided to "differ a bit from the webtoon because [they're] showing on different platforms." Ultimately, the live-action adaptation deviates dramatically from the original.

The series spent most of its budget, with each episode costing ₩3 billion. Choreographer Kim Seol-jin and contortionist Troy James were chosen to record the monsters' movements through motion capture.

Although filming had already started, Netflix officially announced the series' lineup on December 18, 2019, with Song Kang, Lee Jin-wook and Lee Si-young in lead roles, and Lee Do-hyun, Kim Nam-hee, Go Min-si, Park Gyu-young, Go Youn-jung, Kim Kap-soo and Kim Sang-ho as part of the ensemble cast.
