World Cup winners Argentina were greeted by jubilant crowds at Buenos Aires airport and Tuesday has been declared a bank holiday in the country.
The squad, who defeated France in Sunday's final, landed home at 02:24 local time (05:24 GMT) on Tuesday.
Fans lined the streets as they travelled on an open-top bus to their Football Association's headquarters.
The main celebration will be at the capital city's Obelisk monument at midday (15:00 GMT) on Tuesday.
The Argentine government said the day would be a bank holiday so fans "can express their deepest joy for the national team".
Lionel Messi led the team off the plane, which carried his picture on its tail.
