A Dorcas Society is a local group of people, usually based in a church, who make it their mission to provide clothing to the poor.  The original society was founded in the Isle of Man in 1834, following an an outbreak of cholera in the area.  The clothes and bedding of the poorer families in town was destroyed, as part of the effort to prevent the disease.  As part of the community's thanksgiving for being spared from the outbreak, wealthier community members founded the society to assist their destitute neighbours.  

The society is named after Tabitha, also called Dorcas, who appears in the Acts of the Apostles.  Dorcas is Greek translation of the Aramaic name Tabitha.
