Millisecond pulsars are neutron stars that spin hundreds of times a second. Their fantastic rotation rates are commonly believed to be the result of an accretion phase in which an old neutron star accretes both matter and angular momentum from a binary companion, and is "recycled" to become a radio pulsar once again - now spinning much faster than before and with a significantly reduced magnetic field strength. I will discuss our current understanding of radio millisecond pulsars, focusing primarily on those that are found in Galactic globular clusters, but also discussing those objects found in the field.
