The Lord Lieutenant of Caithness is the British monarch's personal representative in an area defined since 1975 as consisting of the local government district of Caithness, in Scotland. This definition was renewed by the Lord-Lieutenants (Scotland) Order 1996. Previously, the area of the lieutenancy was the county of Caithness, which was abolished as a local government area by the Local Government (Scotland) Act 1973. The district was created under the 1973 act as a district of the two-tier Highland region and abolished as a local government area under the Local Government (Scotland) Act 1994, which turned the Highland region into a unitary council area.
