The law on same-sex marriages has already changed in England and Wales.
The change in Scotland comes as a survey revealed a huge rise in support for same-sex marriage over the past 12 years.
More than two-thirds of people (68%) agreed that gay couples should have the right to marry, according to the figures from the Social Attitudes Survey, which tracks public opinions on a range of subjects.
The figure compares with just two-fifths of the public (41%) in 2002.
The 2014 survey suggested fewer than a fifth (17%) of Scots were against same-sex marriage, compared to 29% in 2002.
Younger people were more likely to believe gay couples should be allowed to wed than older Scots, with 83% of 18 to 24-year-olds in favour compared to 44% of those aged 65 and above.
