Cromartyshire is a historic county in the
Highlands of
Scotland, comprising the medieval "old shire" around the
county town of
Cromarty and 22
exclaves transferred from
Ross-shire in the late 17th century. The largest part, six times the size of the old shire, is
Coigach, northwest from
Ullapool. In 1890, Cromartyshire was merged with Ross-shire into the administrative county of
Ross and Cromarty. In 1975, the county was combined with
Caithness,
Inverness-shire,
Nairnshire,
Sutherland, and parts of
Argyllshire and
Morayshire to form the
Highland council area.
