A mercat cross is the Scots name for the market cross found frequently in Scottish cities, towns and villages where historically the right to hold a regular market or fair was granted by the monarch, a bishop or a baron. It therefore served a secular purpose as a symbol of authority, and was an indication of a burgh's relative prosperity. Historically, the term dates from the period before 1707, when the Kingdom of Scotland was an independent state, but it has been applied loosely to later structures built in the traditional architectural style of crosses or structures fulfilling the function of marking a settlement's focal point. Historical documents often refer simply to "the cross" of whichever town or village is mentioned. Today, there are around 126 known examples of extant crosses in Scotland, though the number rises if later imitations are added.

A market cross, or in Scots, a mercat cross, is a structure used to mark a market square in market towns, where historically the right to hold a regular market or fair was granted by the monarch, a bishop or a baron.
