DESCRIPTION:The peculiar (non-Hubble) velocities of galaxies are a direct 
 probe of the matter distribution and the nature of gravity. With the adven
 t of dedicated spectroscopic facilities able to measure thousands of spect
 ra simultaneously\, peculiar velocity surveys are being incorporated withi
 n the new generation of giant galaxy surveys. The sample sizes and volumes
  of peculiar velocity surveys will consequently increase by more than an o
 rder of magnitude\, resulting in hundreds of thousands of peculiar velocit
 ies over the whole sky. This wealth of data is driving a renaissance in th
 e use of peculiar velocities for cosmology. I will briefly summarise scien
 ce results from recent analyses of existing surveys\, report on the status
  of ongoing surveys\, and describe the goals of next-generation surveys.
