# List of Scottish Gaelic surnames

This list of Scottish Gaelic surnames shows Scottish Gaelic surnames beside their English language equivalent.
* Unlike English surnames (but in the same way as Slavic, Lithuanian and Latvian surnames), all of these have male and female forms depending on the bearer, e.g. all Mac- names become Nic- if the person is female.
* Some of the Scottish Gaelic surnames are Gaelicised forms of English surnames; and conversely, some of the English surnames are Anglicised forms of the Gaelic surnames.
* In some cases the Gaelic and English names do not share an etymological origin.
* Several surnames have multiple spellings; this is sometimes due to unrelated families bearing the same surname.
* A single surname in either language may have multiple translations in the other.
* In some English translations of the names, the M(a)c- prefix may be omitted in the English, e.g. Bain vs MacBain, Cowan vs MacCowan, Ritchie vs MacRitchie. Also, the prefixes Mac- and Mc- are interchangeable, although individuals may have a preference as to which form is used in their own surname.
