The move comes in a bid to get more people vaccinated against the virus.
In an address to MSPs Sturgeon said: "Given the current situation – and the need to get more people fully vaccinated before we ease up further – it is reasonable, I think, to indicate now that it is unlikely that any part of the country will move down a level from 28 June.
"Instead, it is more likely that we will opt to maintain restrictions for a further three weeks from 28 June and use that time to vaccinate – with both doses – as many more people as possible.
