Geoff Smith (born 1966) is a British music composer, writer, and academic. Along with his wife, singer Nicola Walker Smith (born 1964), he has written and recorded several pieces of contemporary classical music as well as published the 1995 book New Voices: American Composers Talk about Their Music (alternate title American Originals: Interviews with 25 Contemporary Composers). His compositions have been described as "minimalist" and "pop classical" and he's been compared to contemporaries Philip Glass and Steve Reich.

Many of Smith's musical works take their lyric content from traditional English verse or English Romantic poets including Emily Brontë, John Keats, Christina Rossetti, Percy Bysshe Shelley, and Elizabeth Siddal.
