A cuttie-stool, or cutty-stool (also -stuil), was a type of three-legged chair used in Scotland. It was a short stool, often having a round seat on the top, but the word also designates a larger piece of furniture associated with public penance in church.

Such stools were often used for milking and domestic purposes, and afforded little comfort other than to provide balance to the worker concerned. They were cheap to buy and easy to make, and their three legs made them stable on uneven floors. "Cutty" or "cuttie" means "short" in Lowland Scots, and can be found in such phrases as "cutty sark" (the nickname of the witch in Tam o' Shanter, derived from her only garment, a short shift).
