Griezmann netted at the end of the first half from the penalty spot after a controversial handball decision against Germany’s Bastian Schweinsteiger.
Schweinsteiger conceded the penalty as replays showed his arm grazed the ball as he put his arms up while marking Patrice Evra from a corner.
Griezmann scored again in the second half after a mistake from German goalkeeper Manuel Neuer handed him an easy tap in.
It’s the first time that France have beaten Germany in the finals of a competition since 1958.
