Worlds is the debut studio album by the American electronic music producer Porter Robinson, released on August 12, 2014, by Astralwerks. Initially known for his heavier bass-centric production, Robinson became increasingly dissatisfied with the electronic dance music (EDM) genre, believing it limited his artistic expression. In 2012, Robinson released his first song with a greater emphasis on melody, "Language", and decided thereafter to prioritize aesthetic and emotional qualities in his work. He was inspired by media that evoked nostalgia for his childhood, and wrote music integrating elements taken from anime, films, and sounds from 1990s video games.

Robinson's primary inspirations for Worlds were Daft Punk's Discovery (2001) and Kanye West's Graduation (2007). Critics described the work as electropop, noting similarities to the styles of M83 and Passion Pit. In late 2013, a bidding war broke out among record labels over which of them would release the record. The album was preceded by four singles: "Sea of Voices", "Sad Machine", "Lionhearted", and "Flicker", and promoted with a tour in North America and Europe.

Worlds was well received by most critics, who praised it as innovative and forecasted a promising career for Robinson, though others felt the record lacked coherence or was unexciting. Retrospectively, the album was noted for its impact on the EDM scene. It charted in the United States, the United Kingdom, Australia, and the Netherlands. Following Worlds's positive reception, Robinson felt pressured to write an appropriate follow-up work. As a result, he experienced a period of writer's block and depression, leading to the seven-year gap until his next studio album, Nurture (2021).
