Around 170 discount deals are available at 130 venues for families and tourists on November 30.
In the greater Glasgow area 58 venues are participating, including the City Sightseeing Bus tours which has 2 for 1 tickets.
Several of the city’s attractions, including House for an Art Lover and the Hampden Experience, are offering families a day out for almost half-price.
Culture Secretary Fiona Hyslop said: “St Andrew’s Day is the perfect opportunity for Scots and Scots-at-heart around the world to celebrate all that is great about our nation, including our thriving contemporary culture, our rich heritage and our warm and friendly welcome.
“What better way to enjoy our national day than to gather together friends and family to explore what’s on offer? We want Scots to take advantage of the diverse range of events and activities on their doorstep in Glasgow and celebrate a fun-filled St Andrew’s Day out this year.”
Laura Boyce, her husband Colin and their daughters Olivia, four, and six-month-old Anna were at the Riverside Museum in Glasgow to help launch the programme.
“With money being quite tight for a lot of families, it’s just brilliant to know that you can go out and really enjoy what Scotland has to offer, so many great attractions for all the family to enjoy,”
The St Andrew’s Day Out kicks off the Scottish Winter Festival which runs until Burns Night on January 25 and includes the month-long St Andrews Food and Drink Festival in Fife and street parties in Glasgow and Edinburgh to mark the day.
The Scottish Government says it has spent £350,000 on the Scottish Winter Festival.
