"Priscilla and I are so happy to welcome our daughter Max into this world! For her birth, we wrote a letter to her about the world we hope she grows up in," he said.
"It's a world where our generation can advance human potential and promote equality - by curing disease, personalising learning, harnessing clean energy, connecting people, building strong communities, reducing poverty, providing equal rights and spreading understanding across nations," Zuckerberg said in his post.
"Our hopes for your generation focus on two ideas: advancing human potential and promoting equality. Advancing human potential is about pushing the boundaries on how great a human life can be," he said.
Zuckerberg said he and Priscilla are committing to spending their lives doing their small part to help solve these challenges.
"I will continue to serve as Facebook's CEO for many, many years to come, but these issues are too important to wait until you or we are older to begin this work. By starting at a young age, we hope to see compounding benefits throughout our lives," he said.
In the letter, he announced to begin Chan Zuckerberg Initiative to join people across the world to advance human potential and promote equality for all children in the next generation.
"Our initial areas of focus will be personalised learning, curing disease, connecting people and building strong communities," he said.
"We know this is a small contribution compared to all the resources and talents of those already working on these issues. But we want to do what we can, working alongside many others," Zuckerberg said.
