Andrew Vivian (1759–1842) was a British mechanical engineer, inventor, and mine captain of the Dolcoath mine in Cornwall, England.
In partnership with his cousin Richard Trevithick, the inventor of "high pressure" steam engines, and the entrepreneur Davis Giddy, Vivian financed the production of the first steam carriage and was granted a joint patent for high pressure engines for stationary and locomotive use in March 1802.
