Charles Gaudichaud-Beaupré (September 4, 1789 - January 16, 1854) was a French botanist.

He was born in Angoulême, the son of J-J. Gaudichaud and Rose (Mallat) Gaudichaud. He studied pharmacology at Cognac and Angoulême. He also studied chemistry and herbology.

His greatest claim to fame was serving as botanist on a circumglobal expedition from 1817-1820. He accompanied Freycinet, who made the expedition on the ships Uranie and Physicienne. He is known for his collections in Australia.

He later went on a second voyage to South America, in 1831-1833.

He died in Paris.
