Ronaldo can add the accolade to the league and European trophies he won with Real Madrid last season.
Players and managers from around the world flocked to the London Palladium, suited and booted for the second ever edition of the Best FIFA awards.
And it was Ronaldo who scooped the top award yet again, presented by footballing greats Diego Maradona of Argentina and Brazil's Ronaldo.
"Thank you for voting for me," said Portuguese international Ronaldo. "I want to mention Leo (Messi) and Neymar for being here. I want to thank Real Madrid for their support all year.
"This is a great moment for me. Thank you to all my fans all over the world. I appreciate that. I'm so happy, thank you very much and have a good night!"

Cristiano Ronaldo collects his award as the Best FIFA men's player 2017.
Football's best celebrated
The initial shortlist for the Best FIFA awards is chosen by a panel of former players, with the winners chosen by national coaches and captains, members of the media, and fans.
The star-studded event was hosted by British actor Idris Elba, and the audience was littered with famous footballing names.
For Ronaldo, it was yet another trophy to place in an already bulging cabinet.
The striker helped Real Madrid its first league and European Cup double since 1958 last season -- the first side to win back-to-back Champions League titles in the process.
