Year 485 (CDLXXXV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Memmius without colleague (or, less frequently, year 1238 Ab urbe condita). The denomination 485 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

- Emperor Xiao Wen Di institutes an "equal-field" system of agriculture, assigning each peasant family about 19 acres (140 mu) of land, of which a small portion is to be kept permanently by the farmer and his family, with the rest reverting to the state upon his death or retirement. To make sure that the people supervise each other in implementing the new system, he divides the population into groups, with five families constituting a neighborhood (Jin), five neighborhoods a village (Ji), and five villages an association (tang) headed by a chief (chang). The land-reform system will discourage farmers from selling off their properties to large landholders and will be continued in essence for well over 1,000 years.
