It also ends a almost 11-year major tournament drought for Woods, who last captured one back in 2008 at the US Open.
After a decade without a major that included multiple surgeries, personal scandals, and legal issues, Tiger Woods has won his 15th major title.
It completes a fairytale return for the most dominant player of his generation - and arguably the best ever - after enduring "dark times" through injury since 2014.
Sunday's thrilling victory puts the former world No.1 just three majors behind the all-time record of Jack Nicklaus.
Woods began the day two shots behind Italy's Francesco Molinari, and rode the roller coaster of a gripping final round to first share the lead after the Italian found the water in front of the short 12th. The 43-year-old hit back-to-back birdies at No. 15 and No. 16 to take the sole lead, and he would hold onto it from there despite Brooks Koepka and others chasing. It was his first win at Augusta National since 2005.
