A Greek withdrawal from the eurozone was a hypothetical scenario under which Greece would withdraw from the Eurozone to deal with the now expired Greek government-debt crisis. This conjecture has been referred to as "Grexit", a portmanteau combining the English words "Greek" and "exit", and which has been expressed in Greek as ελλέξοδος, (from Ελλάς + έξοδος). The term "Graccident" (accidental Grexit) was coined for the case that Greece exited the EU and the euro unintentionally. These terms first came into use in 2012 and have been revitalised at each of the bailouts made available to Greece since then.

Proponents of the proposal argue that leaving the euro and reintroducing the drachma would dramatically boost exports and tourism, while discouraging expensive imports, which would give the Greek economy the possibility to recover and stand on its own feet.

Opponents argue that the proposal would impose excessive hardship on the Greek people, as the short-term effects would be a significant consumption and wealth reduction for the Greek population. This may cause civil unrest in Greece and harm the reputation of the eurozone. Additionally, it could cause Greece to align more with non-EU states.
