Paul John Buckmaster (born in 1946 London) is a Grammy Award-winning English artist, arranger and composer.

He began learning the cello at the age of 4 and graduated from the Royal College of Music at age 16.

He is perhaps best known for his orchestral collaborations with Elton John. He has displayed professional mastery as a cellist but he has also worked as an arranger on various hit songs, including David Bowie's "Space Oddity" (1969), and played with Miles Davis on On the Corner, for which he also did the arrangements.

In film, Buckmaster composed the original score for Terry Gilliam's science fiction hit "12 Monkeys," (Universal, 1995), which starred Bruce Willis, Madeleine Stowe and Brad Pitt.

Buckmaster won the 2002 Grammy Award for Best Instrumental Arrangement Accompanying Vocalist(s) for Drops of Jupiter.
