Henry Blunt (1806 -1853) was a British painter, who largely worked using watercolours. He was active as a painter from c.1837 - c.1843. His work is represented in several collections such as that of the British Museum.

Blunt was a chemist and amateur watercolourist. He is perhaps best known for his model of the lunar surface in 1849, which can be seen in the collections of the Science Museum in London.
