Risby is a village and civil parish in the West Suffolk district of Suffolk in eastern England, located around 3 miles west of Bury St. Edmunds, north of the A14 road. It is believed that the village was founded in about the tenth century, presumably on the strength of its having a Norse name, possibly Rȳðs- by "farm settlement at a clearing" and identical to Ryssby in Sweden. The traditional division or Hundred in which it stands is Thingoe, also a Norse name.
