An independence referendum was held in the Latvian SSR on 3 March 1991, alongside a similar referendum in the Estonian SSR the same day. Known as the "Popular Survey about the independence of the Republic of Latvia", voters were asked "are you in favour of a democratic and independent Republic of Latvia". It was approved by 74.9% of voters, with a turnout of 87.6%. Latvian Republic civilians registered in Soviet Army units also had the right to vote in this poll.
The independence of Latvia was finally restored on August 21, 1991.
