The Hollywood star's actress wife, Christine Taylor, gave birth to a baby boy in Los Angeles on July 10, according to America's People magazine.
The couple - who have co-starred in the films 'Dodgeball' and 'Zoolander' - have named their new son Quinlin Dempsey.
Ben and Christine - who married in May 2000 - already have a three-year-old daughter, Ella, who Christine claims is following in her father's footsteps.
She said recently: "It's not even funny how much she is like Ben. She's definitely a ham." Earlier this year, it was claimed Ben would be taking a year off after the birth of his child.
A friend said Ben, who made six movies last year, wants to put family before his busy work schedule.
The pal said at the time: "Ben loves being a father and he feels he's missing out on a lot by working so much.
"He's saying that he's going to take at least a year off to be with his daughter and the baby once it arrives."
But the friend explained that, although he would not be working, Ben would still find the year hard work.
He added: "Christine needs his help as chief diaper changer!"
