Christian Paul Gilbert Estrosi (born 1 July 1955) is a French sportsman and politician and the Mayor of Nice since 2017, previously holding the office from 2008 to 2016.

[1] He was then appointed on 19 June 2007 as Secretary of State for the Overseas French territories (DOM-TOM), this time serving under Michèle Alliot-Marie.

[8] As part of a reorganization of the Union for a Popular Movement (later Republicans) leadership under their chairman Jean-François Copé in January 2013, Estrosi became – alongside Henri de Raincourt, Jean-Claude Gaudin, Brice Hortefeux, Roger Karoutchi and Gérard Longuet – one of the party's six vice-presidents.

[11] Ten months ahead of the election, he and other local conservatives aggressively criticised Socialist Minister of the Interior Bernard Cazeneuve for the lack of strength of the National Police force presence on the night the 2016 Nice truck attack.

[15] On 8 May 2017, the day after the second round of the presidential election, Estrosi announced his resignation from the presidency of the Regional Council of Provence-Alpes-Côte d'Azur to become Mayor of Nice again, succeeding his former first deputy, Philippe Pradal.

Overseeing the local authorities' response to the COVID-19 pandemic in France, Estrosi called in early 2021 for a weekend lockdown in the area to reduce the flow of tourists; at the time, Nice had a level of COVID-19 infections triple the national rate.

[17] In 2021, Estrosi left The Republicans to join Édouard Philippe's Horizons party, after Toulon Mayor Hubert Falco.

Provence-Alpes-Côte d'Azur Regional Council President Renaud Muselier also left The Republicans that year, marking a loss of elected officials in the area for the party.

[18] Estrosi was among conservative politicians in France who backed calls for a ban on the body-covering burkini swimsuit that some Muslim women wear on the beach, which was later invalidated by French courts.
