Keiss Castle is a partially ruined castle in Scotland, which stands on sheer cliffs overlooking Sinclair's Bay less than one mile north of Keiss village centre, Caithness, Highland, Scotland. It is protected as a scheduled monument. The old castle was replaced by Keiss House around 1755.
The castle was constructed as a Z-plan tower house with 4 floors plus an attic and a vaulted basement. It had a pair of corner towers at opposite angles of a square central block, the main tower being very narrow for its height with tall chimneystacks.
