Speaking at the Scottish Government’s coronavirus briefing, she said the latest figures showed no new deaths within the previous 24 hours.
The total number of people who have died under the measurement remains at 2,482.
She said: “This is the fourth day in a row when no deaths of patients confirmed through a test have been recorded in Scotland.”
She added: “Now, of course, two of these days have been weekends and we know that registration can be artificially low at weekends, and we may see more deaths registered later this week.
“But there’s no doubt that these recent figures demonstrate beyond any doubt how much progress Scotland has made in tackling Covid and that is down to the efforts and sacrifices of everyone across the country.
“I want again to say a heartfelt thank you to all of you for that.”
Ms Sturgeon said five more people tested positive for the virus since Sunday, taking the total to 18,241.
A total of 740 patients were in Scottish hospitals with confirmed or suspected Covid-19, down 38 in 24 hours.
Of these, 10 were intensive care, a fall of three.
It comes as shops across Scotland reopen as part of phase two of the Scottish government’s lockdown easing plan.
Ms Sturgeon has urged Scots to continue stick to restrictions on social distancing and wearing face coverings on public transport and enclosed spaces in recent, saying she does not want to see the number of cases begin to rise once more.
