Roy Montgomery (born 1959) is a composer, guitarist and lecturer from Christchurch, New Zealand. Montgomery's mostly instrumental solo works have elements of post-rock, lo-fi, folk and avant-garde experimentation. His signature sound might be described as atmospheric or cinematic, often featuring complex layers of chiming, echoing and/or droning guitar phrases. He is currently head of the Environmental management department at Lincoln University in New Zealand.

Montgomery has played in several New Zealand bands since 1980, most notably The Pin Group, Dadamah, Dissolve and Hash Jar Tempo. He has also released solo albums on labels including [l606] and [l23611].
