Mathew Dawson (1820–1898) was a British racehorse trainer.
In a career which lasted from 1840 until his death in 1898 he trained the winners of twenty-eight British Classic Races, a figure surpassed by only two other men.
He was significant as one of the first trainers to run a public stable, rather than being the employee of a wealthy patron.
He was based for most of his career at Newmarket, Suffolk.
His first name is sometimes recorded as "Matthew", but "Mathew" is more usual.
