Davutoglu will make the visit on the invitation of Hollande and express Turkey's solidarity with the French people, prime ministry sources said.
German Chancellor Angela Merkel, European Council President Donald Tusk, British, Italian and Spanish prime ministers have also confirmed their participation at the rally.
France remained on tenterhooks Saturday as authorities searched for suspects, including wives of three slain gunmen who murdered 17 people, who included leading cartoonists, civilians and police officers in deadly attacks in and around Paris.
One of the main suspects is Hayat Boumediene, a woman said to be closely related to Amedy Coulibaly who had taken hostages at a supermarket in Paris.
All three suspected gunmen, who were involved in the worst terror attacks France saw in decades, were killed Friday, according to authorities.
