The actor welcomed his new son Max Charles Murphy with fiancee Paige Butcher on Friday, his publicist announced.
Weighing 6lbs 11oz, the baby boy is the couple’s second child together, a little brother to Izzy, two.
His middle name is said to be a tribute to Murphy’s older brother and fellow comedian Charlie Murphy, who died of leukaemia last year.
Murphy, 57, and Butcher, 39, an Australian model and actress, have been together since 2012.
The Nutty Professor and Beverly Hills Cop star has eight other children.
His oldest, Eric, whose mother is Paulette McNeely, was born in 1989.
Murphy’s second son, Christian, with his then-girlfriend Tamara Hood, was born a year later.
The star went on to have five children – Bria, Myles, Shayne, Zola and Bella – with his now ex-wife Nicole Mitchell.
He then went on to date Spice Girl Melanie Brown, Mel B, who gave birth to Angel Iris Murphy Brown in 2007.
The actor was famously involved in a custody battle with Brown after demanding a paternity test, saying: “I don’t know whose child that is until it comes out and has a blood test.”
