Richard Henry Nibbs was an English painter and book illustrator who specialised in marine art.

Nibbs was born in Brighton, Sussex (now East Sussex), England and educated at a school in Worthing (run by the father of watercolourist Henry Tidey). He lived in Brighton throughout his life. Nibbs initially trained as a musician and became a professional cellist with the Theatre Royal orchestra. However, a lifelong love of art combined with a natural talent for detailed observation led him to become a self-taught painter - in both oils and watercolour - particularly of marine subjects. In 1840 a substantial inheritance allowed him to devote himself full-time to art.

His marine art depicts scenes mainly off the coast of his native Sussex, France and Holland - though he also drew buildings and landscapes. He exhibited regularly at the Royal Academy, the British Institution and the Royal Society of British Artists.
