It will be the first time SNP leader Ms Sturgeon has spoken at an independence rally since the referendum campaign in 2014.
The first minister told a major rally in Glasgow the time would come to break away from the "chaos of Westminster" in a second independence poll next year.
She added that there was a "huge appetite" for a second Brexit and Scottish referendum in 2020.
And instead, she said: "There is a much better alternative".
Earlier on Saturday, Labour leader Jeremy Corbyn had argued against Scottish independence, saying if he was voted into Downing Street £70 billion of capital spending money would come to Scotland, as well as extra cash for health and education.
Scottish Conservative MSP Annie Wells said: "Annie Wells said: "While Nicola Sturgeon is banging on about indyref2, I'm out talking to people about the state of their local schools, the drug deaths crisis and violent crime taking over our streets, and the problems at the Queen Elizabeth Hospital".

"We are gathered here to demand the right to choose an independent future for Scotland".
The question people are now faced with is whether Boris Johnson or the people of Scotland themselves should control this country's future.
This election is Scotland's chance to escape Brexit and to put our future in our own hands.
The first minister told the crowd the general election was "the most important election for Scotland in our lifetimes". "She is showing everyone that her priority is indyref2 above everything else".
Scottish Labour leader Richard Leonard said: "Nicola Sturgeon has launched a wave of attacks against the Labour Party as she knows we are her biggest threat in this election".
Scottish Conservative acting leader Jackson Carlaw said: "Nicola Sturgeon and I can finally agree on one thing".
The Scottish independence movement could reignite divisions in next month's vote.
