MSPs voted by 69 to 59 in favour of seeking permission for a referendum before the UK leaves the EU.
Ms Sturgeon says the move is needed to allow Scotland to decide what path to follow in the wake of the Brexit vote.
But the UK government has already said it will block a referendum until the Brexit process has been completed.
Prime Minister Theresa May, who met Ms Sturgeon for talks in Glasgow on Monday, has repeatedly insisted that "now is not the time" for a referendum.
Her Scottish secretary, David Mundell, has said that the timescale could include "the Brexit process, the journey of leaving and people being able to understand what the UK's new relationship with the EU is, so they can make an informed choice if there was ever to be another referendum".
