The Inter Miami forward, 39, also became an eight-time Ballon d’Or winner and won the Champions League four times with Barcelona, plus 10 La Liga titles in 17 seasons in their first team.
Jorge supported his local team Newell’s Old Boys and Lionel joined the club when he was seven years old.
The family relocated to Spain in February 2001 after Lionel was signed by Barca aged just 13, and although Messi’s mother and three siblings soon moved back to Rosario, his father stayed with him in Barcelona.
“Jorge was the pillar and the person who supported with vision, rigor and affection the career of the greatest player of all time alongside his wife, Celia Cuccittini,” Newell’s Old Boys posted on X., external
“His constant companionship and behind-the-scenes leadership were essential in backing every step of Lionel, from his beginnings at Malvinas [youth academy] to the pinnacle of world football glory.
“Thank you for teaching him to love these colours.”
The club added that they “embrace with affection Celia, Lionel, Rodrigo, Matias and Maria Sol, and all their loved ones and close ones in this difficult moment”.
Barcelona thanked Jorge “for his commitment to our club, for entrusting us with the beginnings and the most glorious years of his son Leo’s football career”.
The Argentine Football Association said it “deeply mourns with sadness and sorrow the passing of Jorge Messi, father of our captain and emblem, Lionel Messi”.
It added: “From here, we stand in solidarity with the entire family during this difficult time and send the most heartfelt, warm and affectionate embrace.”
The Messi family responded after an Argentine television presenter falsely reported Jorge had died during Argentina’s opening game at this summer’s World Cup.
The presenter later resigned, while the family expressed their “deep discomfort with the lack of sensitivity, respect and discretion with which some people have treated what is strictly a private family matter”.
