The result of the referendum may be a foregone conclusion but the Island's Government - and Britain - hopes it will send a signal.
Next week's islanders are expected to vote overwhelming to remain an Overseas Territority of the UK, but will Argentina listen?
Britons are supposed to be renowned for their manners - but a survey has found nearly 80% of Britons think bad manners are getting worse.
Falklands United on behalf of the Falklands United Movement have launched an outspoken attack on President Cristina Kirchner of Argentina in a statement released after the referendum results.
Tonight the Government of Argentina and the rest of the world heard our voice. It is a Falklands voice. It is a British voice.
Tonight is without doubt a very special moment for Falkland Islanders but even more so for democracy.
We have been treated by the Argentine Government as if we don’t exist – or at least as if we have no rights. We have been told that within twenty years our home will be under the control of a nation that we know does not have our best interests at heart. This will never happen and we have resolutely voted against that.
Argentina must pay attention and accept the result of our referendum. Failure to do so suggests that they have priorities other than democracy and freedom of people to choose their own future. In the modern world surely these priorities must be condemned.
These messages have been humbling and a sign that in addition to most of South America, Argentine citizens are growing tired of the Kirchner Government.
UK Representative for the Falklands Islands Government, Sukey Cameron, told Daybreak that the referendum result has shown the world that the Falklands has "a voice."
She said the rest of Southern America is coming round to the idea that the Falklands will stay British.
Mrs Cameron added that they had received a "lot of supportive tweets from people in Argentina."
Journalist Celina Andreassi, from the Argentina Independent in Buenos Aires, said the strength of the Yes vote had been "quite predictable".
The majority of people here agree with the official position, that the issue is not about self-determination and it is not about whether the islanders consider themselves British or not, because obviously everyone knows that they do and that they are British.
The issue for most people here is that whether the territory is Argentine or British, not the people themselves.
I really don't think this referendum is going to make much of a difference... both sides are going to remain really strong in their position and we are probably going to continue where we are for a long, long time.
Following the referendum result Foreign Secretary William Hague said: "I welcome today's result, which demonstrates more clearly than ever the Falkland Islanders' wish to remain an Overseas Territory of the United Kingdom.
"We have always been clear that we believe in the rights of the Falklands people to determine their own futures and to decide on the path they wish to take. It is only right that, in the 21st century, these rights are respected.
"All countries should accept the results of this referendum and support the Falkland Islanders as they continue to develop their home and their economy. I wish them every success in doing so."
Falkland Islanders celebrated on the streets of Stanley after hearing the overwhelming 'Yes' result of a sovereignty referendum.
A total of 1,513 votes were cast in the referendum, a turnout of 92% of the islanders eligible to vote.
Just three votes, or 0.2% of the ballot, were against the referendum, which asked: "Do you wish the Falkland Islands to retain their current political status as an Overseas Territory of the United Kingdom?"
The Falkland Islands voted overwhelmingly today to remain an overseas territory of the United Kingdom, with 98.8% voting in favour.
A referendum representative said only three votes (0.2% of the total) voted against remaining British.
Voting in the Falkland Islands sovereignty referendum closed at 11pm UK time.
A result is expected in the early hours of Tuesday morning.
Falkland Islanders have just a few hours left to vote in a referendum on whether they want to remain a British overseas territory.
The outcome is expected to be strongly in favour, although this may ultimately have little impact on the dispute with Argentina which has said it does not recognise the referendum.
ITV News' International Editor Bill Neely reports from Buenos Aires in Argentina:
Counting will begin in a referendum over whether the Falkland Islands should remain British today.
Falklands War veteran, Simon Weston said this was "just another step to improving democracy and self determination."
The community is expected to vote in favour of retaining its status as an Overseas Territory of the United Kingdom.
Mr Weston added: "These are people who have the right to choose whose flag flies over their country, they don't want the Argentinians', and the Argentinians can't afford them."
