St Andrew's Day in 2005 will be a national day of celebration based on the theme of One Scotland, Many Cultures, the first minister has said.
The campaign was launched in 2002 to celebrate a multi-cultural society
Jack McConnell said he wanted 30 November to become a day on which the whole country united to demonstrate Scotland's diversity.
Mr McConnell was addressing a global audience during a special webcast.
Public, private and voluntary sectors will be issued with guidance on how they can participate.
Mr McConnell said that the worldwide reputation of the Scots was the envy of many small nations and was destined to become even more positive in the future.
The Scottish Executive has decided to have a different theme to mark St Andrew's Day each year and chose One Scotland, Many Cultures for 2005.
The campaign was launched in 2002 to raise public awareness of racist attitudes and highlight the damage they cause in Scottish society.
It also aims to celebrate the diversity of a multi-cultural Scotland.
The first minister said: "I want all of Scotland to take part in celebrating our national day.
"Scotland has much to be proud of and much to celebrate. For centuries Scots have travelled around the globe, innovating and making the discoveries that have changed the world.
"But Scotland is also a welcoming nation, one that is open to new ideas and to new people."
Mr McConnell urged people in Scotland to think of ways they could help to mark the date.
"The One Scotland, Many Cultures theme will allow us to celebrate our national identity in a positive, diverse way, not just in an exclusive, traditional Scottish way," he added.
