Tiger Woods' Girlfriend Lindsey Vonn -- Golf DESERVES to Be an OLYMPIC SPORT

Maybe she's biased, maybe she means it ... but Tiger Woods' girlfriend Lindsey Vonn tells TMZ she thinks GOLF absolutely deserves to be re-included in the Summer Olympics.

FYI -- golf hasn't been an Olympic sport since 1904 (when Tug of War was still included in the Games) ... but it will make its return in 2016.

There's been some controversy, with critics saying the golfers won't really care -- they're more interested in a green jacket than a gold medal.

As for Tiger, he's said that he WILL compete in the 2016 Olympics ... if he qualifies.
