Abbas' participation comes a day after he called French President Francois Hollande to express his outrage and condemnation of the attacks, which left 16 civilians dead.
Abbas told Hollande Saturday that the Palestinian people and leadership would remain supportive of France against "this terrorism which has no religion," official Palestinian news agency Wafa reported.
Abbas expressed his condemnation and strong opposition to any "terror attack" that hurts innocent citizens, regardless of whether the victims are Christians, Jews, Muslims, or followers of any other religion or creed.
"Human life is sacred and God has created us all," he reportedly said.
A number of leaders from Arab and Muslim countries will also join the rally in Paris Sunday alongside Abbas.
Many around the world have taken pains to stress that Islam is a religion of peace and that the attackers represent only themselves, not the faith as a whole nor the beliefs of Islam's 1.6 billion followers.
