Who Was Denny Hamlin’s Father? About Dennis Hamlin
Dennis was unfortunately dying before the December 2025 house fire. In October of that year, Denny opened up about his late father’s influence on his racing career, telling the Associated Press that his dad took out several mortgages on his Virginia home and nearly went broke while helping his son get into NASCAR.
“I know for a fact this is my last chance for my dad to see it,” Denny told the AP at the time, explaining that Dennis wasn’t able to watch his NASCAR race that month. “I don’t want him going and never getting to see the moment.”
Denny added that his dad was always a “big hype guy” and consistently told his son that he was the “best.”
“He was just so happy, and he always tells me I’m the best, no matter if I win or not, he always says I’m the best,” the stock car racer said. “He’s a big hype guy, and I sat in his garage and talked with him, he’s got all my old memorabilia and it’s just good to reminisce. He’s a reminiscent guy and right now I am just cherishing those hours that I have with them each week.”
