At Facebook's current value, the donation amounts to £30bn. The shares will be donated over the course of the couple's lives.
Max was born last week and her arrival was announced on Tuesday.
In his letter, Mr Zuckerberg said that the aim of the Chan Zuckerberg Initiative is "to advance human potential and promote equality for all children in the next generation." It focuses on personalised learning, curing disease, connecting people, and building strong communities.
Addressing his daughter, he wrote: Your mother and I don't yet have the words to describe the hope you give us for the future."
"You've already given us a reason to reflect on the world we hope you live in."
In a filing to the US Securities and Exchange Commission, Facebook said that Mr Zuckerberg "plans to sell or gift no more than $1bn of Facebook stock each year for the next three years and that he intends to retain his majority voting position...for the foreseeable future."
