David J. Asher (born 1966, Edinburgh) is a British astronomer, who works at the Armagh Observatory (IAU code 981) in Northern Ireland. 
He studied mathematics at Cambridge and received his doctorate from Oxford. 
He is known for the meteor research that he conducts with Robert McNaught.
In 1999 and 2000, they accurately gauged when the Leonids meteor shower would peak, while underestimating the peak intensities.
