Craig Armstrong OBE (born 1959) is a Scottish composer of modern orchestral music, electronica and film scores.
Armstrong was born in Glasgow, Scotland in 1959. He studied musical composition, violin and piano at the Royal Academy of Music from 1977 to 1981, where he was awarded the Charles Lucas prize and the Harvey Lohr scholarship for composition. He was also awarded the FTCL Fellowship in composition, and won the GLAA Young Jazz Musician of the Year in 1982. Upon completing his studies, Armstrong served as music and dance specialist at the Strathclyde Regional Council in 1984.

Armstrong's score for Baz Luhrmann’s groundbreaking musical Moulin Rouge! earned him AFI’s Composer of the Year, a Golden Globe for Best Original Score of the Year and a BAFTA for Achievement in Film Music. His score for Phillip Noyce’s The Quiet American garnered him the Ivor Novello Award for Best Original Film Score. His other feature film scoring credits include the Oliver Stone drama World Trade Center; the Oscar®-winning bio-pic Ray for which Armstrong was awarded a Grammy for Best Original Score; and the worldwide ensemble comedy smash Love Actually. His scores can also be heard in The Magdalene Sisters, Kiss of the Dragon, The Bone Collector, The Clearing, Plunkett & Macleane, Best Laid Plans, Orphans, Elizabeth: The Golden Age and most recently Louis Leterrier’s Incredible Hulk. His score to William Shakespeare’s Romeo + Juliet (again with Baz Luhrmann) also earned him a BAFTA for Achievement in Film Music and an Ivor Novello.
