Cote d'Azur derby called off at government's request
The LFP said the game at the Stade Louis II had been called off following a request by the government in the Mediterranean principality, "in collaboration" with authorities in the neighbouring French Alpes-Maritimes prefecture, which includes Nice.
Paris has been the scene of violent protests for three weekends running from "yellow vest" demonstrators unhappy at planned fuel tax rises.
Demonstrations turned particularly violent last Saturday, with 412 people arrested after the worst clashes in central Paris for decades.
However, unrest has also spread across the country, turning into a broader challenge to President Emmanuel Macron's agenda and complaints that he is out of touch with the struggles of ordinary people. A new round of protests is expected this weekend.
The Cote d'Azur derby was due to see Monaco take on a Nice side coached by Patrick Vieira, Henry's former teammate at Arsenal and the French national side.
Henry oversaw just his second win in 10 games in charge of struggling Monaco as they beat Amiens 2-0 away on Tuesday with a brace of penalties by Radamel Falcao, but the 2017 champions remain in the bottom three.
