Concrete Utopia (Korean: 콘크리트 유토피아) is a 2023 South Korean disaster-thriller film directed by Um Tae-hwa, who wrote the screenplay with Lee Shin-ji, based on the second part of the webtoon Pleasant Outcast by Kim Soongnyung. It stars Lee Byung-hun, Park Seo-joon, and Park Bo-young.

Concrete Utopia is set in Seoul shortly after a titanic earthquake destroys the city, and follows the residents of a building that miraculously remained intact. As they try to survive, they are faced with harsh realities and difficult moral decisions. The film was theatrically released on August 9, 2023.

The film received generally positive reviews from critics and was selected as the South Korean entry for the Best International Feature Film category for the 96th Academy Awards. However, it did not make it to the shortlist. A standalone sequel titled Badland Hunters, following a different set of characters evolving in post-earthquake Seoul, was released in January 2024, with producer Byun Seung-min as the only returning key crew member.
