It is suggested that fast radio bursts can probe gravitational lensing by clumpy dark matter objects that range in mass from 10−3M⊙ to 102M⊙. They may provide a more sensitive probe than observations of lensing of objects in the Magellanic Clouds, and could find or rule out clumpy dark matter with an extended mass spectrum.
