This is a list of Category A listed buildings in the Orkney council area in central Scotland.

In Scotland, the term listed building refers to a building or other structure officially designated as being of "special architectural or historic interest".^[1] Category A structures are those considered to be buildings of "national or international importance, either architecturally or historically".^[1] Listing was begun by a provision in the Town and Country Planning (Scotland) Act 1947, and the current legislative basis for listing is the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997.^[1] The authority for listing rests with Historic Environment Scotland, an executive agency of the Scottish Government, which inherited this role from the Scottish Development Department in 1991. Once listed, severe restrictions are imposed on the modifications allowed to a building's structure or its fittings. Listed building consent must be obtained from local authorities prior to any alteration to such a structure. There are approximately 47,000 listed buildings in Scotland, of which around 8 percent (some 3,800) are Category A.^[1]

The council area of Orkney comprises an archipelago of around 70 islands, including 20 inhabited islands with a total population of around 20,000. There are 20 Category A listed buildings on the islands.
