The multi-year project will transform Walt Disney Studios Park and see the addition of three new areas, along with other new attractions.
Disney said the development would be rolled out over several years, starting in 2021.
In addition to the three new areas, the plan includes a new lake, which will be the focal point for entertainment and will also connect each of the new park areas.
Robert Iger, chairman and chief executive officer of the Walt Disney Company, said: “We’re very excited about the future of Disneyland Paris and continue to invest in its long-term success.
“The resort is already the leading tourist destination in Europe, and the transformative expansion we announced today will add even more of our beloved characters and unparalleled storytelling to create new lands, attractions and entertainment that further elevate the guest experience and drive new opportunities for tourism in this dynamic region.”
