For the first time in eight years, Greece is now free to borrow money on the financial markets
The European Stability Mechanism (ESM) provided the country with €61.9 billion (£55 billion; $70.8 billion) over the three years, BBC reported.
This supported the Greek government's efforts to reform the nation's troubled economy and recapitalize its banks.
Together with assistance from International Monetary Fund, the loans given to Greece since 2010 amounted to more than €260 billion — the biggest bailout in global financial history.
As a condition of the loans, the Greek government was forced to introduce a series of unpopular austerity measures.
The Greek economy has grown slowly in recent years and is still 25 percent smaller than when the crisis began.
The ESM is a fund set up by the countries that use the euro currency to deal with a financial crisis.
It had made available another $27 billion to Greece, but said the country had not needed to call on it.
"Greece can stand on its own feet," said ESM chairman Mario Centeno.
He thanked the Greek people for their co-operation, and also said there would be "no more follow-up rescue programs" for the first time since 2010.
However, Greece's freedom to manage its own economic affairs will be tempered by enhanced surveillance from the European Union's executive, the European Commission. This is designed to ensure Athens does not backtrack on reforms agreed with its lenders. Eventually, the bailout loans will have to be repaid.
Professor Kevin Featherstone, director of the Hellenic Observatory at the London School of Economics, said Greece had helped to safeguard the future of the eurozone by agreeing to the terms of the bailout program.
"By enduring this period of austerity we have avoided a Grexit [Greek exit from the European Union].
"It's certainly the case that the third bailout of 2015 imposed terms which were very, very demanding and very painful indeed.
"For a political system to have gone through these years of austerity, this depth of economic hardship, and maintained a functioning society, a functioning democracy, is testament to the robustness of Greece as a modern state. Greece has saved the euro."
