The Alexians, Alexian Brothers or Cellites are a Catholic religious institute or congregation specifically devoted to caring for the sick which has its origin in Europe at the time of the Black Death. They follow the Augustinian rule.

The Alexians trace their origin to the early 12th-century Beghards, male counterparts of the Beguines, the lay women who followed a devout style of life in a limited degree of common life. The men did not get much attention until they made a great contribution in history in the city of Mechelen, in the Duchy of Brabant (in central Flanders, now Belgium), some time in the 14th century, during the terrible ravages of the Black Death. Some laymen united under the guidance of a certain Tobias to succor the plague-stricken, without taking any vows or adopting a rule of life. One of their most obvious activities was caring for those stricken with the bubonic plague, along with their families, and burying those who died. These laymen lived in little rooms or cells (from Latin "cella," a cell that gave rise to their early name of "Cellites").
