Lionel Messi has three children. He and his wife, Antonela Roccuzzo, have three sons: Thiago, Mateo and Ciro.
Thiago was born in November 2012, Mateo in September 2015 and Ciro in March 2018. The family lived in Barcelona for many years while Messi played for FC Barcelona, later moving to Paris when he joined Paris Saint-Germain and then to South Florida after his move to Inter Miami.
Messi occasionally discusses fatherhood in interviews, but his children have generally been kept away from the most intrusive parts of public attention. All three have shown an interest in football, and they have appeared in youth football settings connected with Inter Miami, although their future careers remain their own choice.
The answer is sometimes confused because Messi has spoken about wanting a daughter after the birth of his third son. That expressed wish does not change the factual count: his children are Thiago, Mateo and Ciro, making three in total.
