A slim majority of as a result of the UK's decision to leave the European Union.
The new poll released today by YouGov shows 51 per cent would back a move to break away from the UK.
It's the first time since 2015 the pollster has found a majority backing for a Yes vote, and comes a day after the Scottish Parliament voted in favour of a new poll.
MSPs argued that Britain's impending departure from the European Union, which a majority of Scots opposed, had changed the circumstances.
First Minister Nicola Sturgeon wants to hold another referendum but Prime Minister Boris Johnson has refused permission, and no vote can take place without the consent of the government in Westminster.
In 2014, Scots voted to remain in the United Kingdom by 55 to 45 per cent.
The poll found that more than one in five of those who voted 'No' in 2014, but backed staying in the EU, would now back independence.
However, a majority of Scots opposed holding a second vote on the issue this year, and the survey found that many voters thinking an independent Scotland would be worse off against 35 per cent believing it would be better off.
"These are concerning times for unionists both north and south of the border with 'Yes' gaining considerable ground on 'No' since 2014," said Chris Curtis, political research manager at YouGov.
"Yet the fundamental problem that flummoxed the 'Yes' movement in 2014, that independence would damage the economy, still exists and could still set them back in indyref2."
Since the 2014 vote, most polls have suggested that Scots would narrowly reject independence again.
However Sturgeon's Scottish National Party, which strongly opposed Brexit, won 48 of Scotland's 59 seats in Britain's national election in December, taking 45 per cent of votes cast, an eight percentage-point increase from 2017.
