First Minister Nicola Sturgeon attended a service at St Giles Cathedral as the city remembered soldiers who lost their lives in battle.
She laid a wreath on behalf of the people of Scotland during the service.
Ms Sturgeon said: “Remembrance Sunday is an opportunity for all of Scotland, in common with people in many other nations across the world, to pause in sombre reflection to commemorate the loss of life in conflicts large and small over the last century.
“It is a chance to honour the memory of those who have made the ultimate sacrifice, while also paying tribute to our veterans and those who continue to serve today.
“The laying of a wreath is a small but significant tribute, and I am privileged to do so on behalf of the people of Scotland.”
Other political leaders also spoke ahead of attending services.
Scottish Labour Leader Kezia Dugdale attended the event in the capital, while shadow Scottish secretary Ian Murray was at a service at a church in his Edinburgh South constituency.
Ms Dugdale said: “Today we remember the sacrifices of all the courageous men and women who died serving our country, whose actions kept our nation safe and who we have to thank for defending our freedom. From the Great War to Afghanistan, we owe a debt to every member of our Armed Forces who fought for this country.
“We also remember today the families they left behind who had to carry on their lives without them.”
Mr Murray said: “Today, people will gather at war memorials, in churches and in community halls across Scotland to mark the sacrifice of the men and women of our Armed Forces. Every community in Scotland was touched by the Great War 100 years ago, and many more have been touched by conflict since.”
Scottish Conservative leader Ruth Davidson said: “Remembrance Sunday is a worthwhile reminder of the sacrifices made, in past decades and today, by those in our Armed Forces. Their fearless and selfless actions ensure we can live freely and safely.
“I for one will be making sure I take the time to acknowledge and remember their efforts.”
