Alexis Tsipras asked supporters for a clear mandate to enable him to end Greece’s austerity policies.
He repeated his promise to have half of Greece’s international debt written off when the current bailout deal ends.
Greece has endured deep budget cuts tied to the massive bailout.
The country’s election on January 25 is being closely watched by financial markets which fear that a Syriza victory could lead Greece to default on its debt and exit from the euro.
“On Monday, national humiliation will be over. We will finish with orders from abroad,” Alexis Tsipras told thousands of cheering supporters at the party’s final election rally in Athens.
“We are asking for a first chance for Syriza. It might be the last chance for Greece.”
Greece has gone through a deep recession and still has a quarter of its workforce unemployed.
However, there have been warnings that a Syriza victory could lead to a dangerous confrontation with other eurozone countries.
Syriza is tipped to win but without an outright majority, and analysts say the party may struggle to find a coalition partner.
Alexis Tsipras has said he will not govern with those who support what he has called the policies of German Chancellor Angela Merkel.
Germany is seen in Greece as taking the hardest line on its debt.
Earlier this month, a spokesman for Angela Merkel said Germany expected Greece to uphold the terms of its international bailout agreement.
Under those terms, the EU, International Monetary Fund and European Central Bank – the so-called troika – supported Greece with the promise of €240 billion in return for budget cuts and economic reforms.
Latest polls show Syriza widening its lead over PM Antonis Samaras’s centre-right New Democracy party.
A poll to be published on January 23 by Metron Analysis put Syriza’s lead over New Democracy up to 5.3 percentage points from 4.6 points.
Another poll, by Rass, had Syriza 4.8 points in the lead.
Antonis Samaras will hold his final election rally on January 23 as both sides make a final push to win over undecided voters.
