This is a timeline of activities either claimed or carried out by the Scottish National Liberation Army (SNLA), a Scottish nationalist paramilitary organisation who advocate for Scottish independence from the United Kingdom. The group formed in 1980, following the 1979 Scottish devolution referendum, which saw a majority voting in favour of a devolved government, but the act was repealed due to a low voter turnout per the Scotland Act 1978.
