Tiger Woods has announced the passing of his mother, Kultida, who died Tuesday morning at the age of 78.

“With heartfelt sadness, I want to share that my dear mother, Kultida Woods, passed away early this morning,” Woods wrote in a post on X. “My Mom was a force of nature all her own, her spirit was simply undeniable. She was quick with the needle and a laugh. She was my biggest fan, greatest supporter, without her none of my personal achievements would have been possible.

“She was loved by so many, but especially by her two grandchildren, Sam and Charlie. Thank you all for your support, prayers and privacy at this difficult time for me and my family. Love you Mom.”

Kultida met Tiger’s father, Earl Woods, in Thailand in 1966 while he was stationed there during the Vietnam War. Three years later, the couple tied the knot in Brooklyn.

Tiger Woods, now 49, once referred to his mother as “the enforcer” during a 2017 interview with USA Today.
