In reaching the finish first in his Polo, Ogier became only the fifth non-Nordic driver to win the classic test of driving skill around the lakes and forests of Finland.
"I had a dream about winning here," the Frenchman said.
"A lot of points for the championship and victory in Finland make it a perfect weekend."
Huge crowds packed the stages in central Finland where four drivers led during the opening seven tests and only 11 seconds covered the top four at the mid-point.
Ogier built a comfortable lead on Friday and was able to drive within himself on the final day when battle raged for second place between Ford Fiesta drivers Neuville and Norwegian Mads Ostberg - the duo trading places through the final stages.
Ostberg span off while avoiding a large rock in the penultimate stage and ended up 21 seconds adrift of Neuville.
"It's an unbelievable feeling," said the Belgian. "We did a great job. Yesterday we lost time with a puncture but otherwise it was a smooth, clean run. Before the rally I couldn't have imagined this result was possible."
