Ardclach Bell Tower is an historic structure in Ardclach, Scottish Highlands. Dating to at least 1655, it is now a Category A listed building. It is believed to be the only tower and belfry combination in Scotland.
The structure, erected as a tower, belfry and keep, is a simple square with a two-storey tower with a double pitched roof. It is harled with ashlar dressings.
A monogram, "MGB", above the second-storey fireplace, refers to Margaret Grant Brodie, wife of Alexander Brodie of Lethen.
