He died at home on Friday, the LSU statement said. No cause of death has been released.
Josh Maravich was a reserve for LSU — which plays home games in the Pete Maravich Assembly Center — from the 2001-02 to 2004-05 seasons under then-coach John Brady.
For the younger Maravich, it was a childhood dream to play for LSU, where his father set the men's NCAA Division I scoring record of 3,667 points between 1967 and 1970.
"I wanted to come here for my dad to make him proud," Josh Maravich said in a 2005 article in The Daily Reveille, the LSU student newspaper. "I knew I wasn't going to be a star player, but for me being a walk-on was what I always wanted to do."
Pete Maravich was a prolific scorer during an NBA career that was cut short in 1980 by lingering effects of a major knee injury a couple years prior.
In 1988, at age 40, he died from a heart condition that had gone undetected.
Earlier this year, he was back in the headlines when his Division I scoring mark — which went unmatched by any men's or women's player for more than half a century — was surpassed by Iowa star Caitlin Clark (3,951 points).
In 2022, when LSU unveiled a bronze statue of Pete Maravich outside its basketball facility, sculptor Brian Hanlon credited Josh Maravich and his older brother Jaeson Maravich with the idea to depict their father — who was known for his showmanship and creativity — making a behind-the-back pass.
