He will become only the second pope to visit Morocco, after Saint John Paul II travelled there in 1985.
The pontiff accepted an invitation from bishops and Morocco's King Mohammed VI for a two-day trip commencing on 30th March 2019. He will visit the capital, Rabat, and Morocco's biggest city, Casablanca.
The Archbishop of Rabat, Cristóbal López said the first papal visit had not been forgotten and it brought "great hope, love and blessings".
In a letter, Archbishop Cristóbal said: "The mission of the Pope is of confirming us in our faith".
He added that the Catholic leader wants to "get to know us, share parts of our life, encourage us, pray with us and bless us."
The Vatican has already confirmed Pope Francis will spend four days in the Central American nation of Panama in January for the World Youth Day festival.
The pope has also been invited to visit Japan, Mozambique and Romania next year.
A report published by the US State Department in 2010 stated that Morocco is 98.7 per cent.
In August, Pope Francis made a 36-hour visit to Ireland.
