The Mechanical-Copyright Protection Society (MCPS) is a UK-based organization established in 1910 to safeguard the rights and collect royalties for its members, including music publishers, songwriters, and composers, when their works are reproduced in various formats such as physical products, streaming services, synchronization in audiovisual entertainment, and radio broadcasts. With over 30,000 members, MCPS operates under the MPA Group, ensuring that creators receive fair compensation for the use of their music.

MCPS has played a pivotal role in the music industry, co-forming the MCPS-PRS Alliance (now known as PRS for Music) in 1997 to facilitate the growth of digital music services while protecting members' rights and collecting royalties. The organization continues to adapt to industry changes, recently announcing a new strategic alliance with PRS until 2025, fostering closer collaboration to better serve the interests of its members.
