The 28-year-old Bayern Munich player was presented with the award at Rio de Janeiro's Maracana Stadium moments after the triumph.
"It is unbelievable, and an awesome experience," said Neuer of his side's victory, which gave Germany their fourth world title.
"We have had incredible cohesion since the start of our preparations. We have had our share of setbacks, including losing players like Lars and Sven Bender, as well as Marco Reus, who all deserve to be world champions.
"Germany are world champions. I don't know how long we will celebrate, but we will go about it with big grins."
The former Schalke goalkeeper was beaten only four times in the tournament and kept four clean sheets, including the 1-0 quarter-final win over France and the victory over Argentina in the final.
