Thomas Tunnock Limited, commonly known as Tunnock’s, is a family baker based in Uddingston, Scotland. It is currently headed by Boyd Tunnock C.B.E., grandson of Thomas. In 2013 a joint report by Family Business United and Close Brothers Asset Management named it as the 20th oldest family firm in Scotland still in operation.

The face of the Tunnock’s Boy appears on nearly all Tunnock’s products. Factory tours have become so popular that the firm keeps a two-year-long waiting list to manage demand.
