Tamilrockers is a notorious online platform known for leaking copyrighted content, primarily movies, before or shortly after their official release. Founded in India, it has gained notoriety for its extensive library of pirated films, often available in multiple languages, including Tamil, Telugu, Hindi, and more. Despite legal efforts to shut it down, Tamilrockers continues to operate by constantly changing its domain names and using proxy servers to evade authorities.

The website operates on a peer-to-peer file-sharing protocol, allowing users to download movies and TV shows illegally. It earns revenue through advertisements and has faced criticism for causing significant financial losses to the entertainment industry by distributing films without authorization. Authorities have periodically cracked down on Tamilrockers, leading to arrests and site blocks, but its resilient network and decentralized structure have enabled it to persist.

Efforts to combat Tamilrockers include anti-piracy laws, stricter enforcement, and promoting legal alternatives like streaming services. However, its popularity remains due to the accessibility and wide range of content available for free. Despite warnings about malware and cybersecurity risks associated with illegal downloads, Tamilrockers continues to attract users seeking free access to the latest movies, making it a persistent challenge for both the entertainment industry and law enforcement worldwide.
