The lunch at Macron's Elysee Palace residence — in a “private” capacity, the presidency said Thursday — will come as Obama visits Paris to speak to Les Napoleons, a network of communications professionals.
Obama, who publicly endorsed Macron during his election campaign, will arrive in Paris on Friday where he is due to make an appearance at the bi-annual “Napoleons” summit as the special guest.
He will give a speech at the Radio France auditorium.
Macron has invited him for lunch on Saturday although the venue remains a secret. The lunch meeting has not been announced officially as the Elysée Palace are apparently concerned about irritating current US president Donald Trump, who they fear may take offence.
It is unlikely Obama will be given the same treatment Trump was given during his summer visit to Paris, when he and his wife Melania were wined and dined at the Jules Verne restaurant on the first floor of the Eiffel Tower.
Trump however has not been invited to the December 12 climate summit in Paris, unlike 100 other leaders, and Macron has also said he wants to save the Iranian nuclear deal despite Trump's opposition.
Last time Obama was in Paris in December 2015 he dined with then French president François Hollande at L'Ambroisie, a restaurant with three Michelin stars in the swanky Place des Vosges square.
He had apparently asked Hollande if they could eat out rather than at the Elysée Palace.
Obama is also due to meet Hollande during his latest trip to Paris but not his predecessor Nicolas Sarkozy.
