Mayer, posting on her blog, said she and her husband are expecting the twin girls in December.
"I have some exciting news to share — I'm pregnant!" the 40-year-old executive wrote on her Tumblr posting Monday night.
Mayer said the twins were "quite a surprise, because I have no family history of twins or any other predisposing factors."
She said that she will take some limited time away but work during the pregnancy as she did with her son's birth three years ago.
Mayer said that she has informed Yahoo executives of her pregnancy.
Three years ago, Mayer announced she was pregnant with her son on her social networking accounts just a few hours after Yahoo hired her as its third full-time CEO in less than a year.
