Corn dollies or corn mothers are a form of straw work made as part of harvest customs of Europe before mechanization.

Before Christianisation, in traditional pagan European culture it was believed that the spirit of the corn (in modern American English, "corn" would be "grain") lived amongst the crop, and that the harvest made it effectively homeless. James Frazer devotes chapters in The Golden Bough to "Corn-Mother and Corn-Maiden in Northern Europe" (chs. 45-48) and adduces European folkloric examples collected in great abundance by the folklorist Wilhelm Mannhardt. Among the customs attached to the last sheaf of the harvest were hollow shapes fashioned from the last sheaf of wheat or other cereal crops. The corn spirit would then spend the winter in this home until the "corn dolly" was ploughed into the first furrow of the new season. "Dolly" may be a corruption of "idol" or may have come directly from the Greek word eidolon, that which represents something else.

James George Frazer discusses the Corn-mother and the Corn-maiden in Northern Europe, and the harvest rituals that were being practised at the beginning of the 20th century:
