The president's official partner is Valerie Trierweiler, 48, a journalist who writes for Paris Match magazine and has presented discussion programmes on French television. She moved in with Francois Hollande after his official separation from Segolene Royal in 2007, and was divorced from her own husband, with whom she has three children.
When Mr Hollande was elected president in 2012, Ms Trierweiler moved into the Elysee palace with him and accompanies him on official trips. She incurred Mr Hollande's wrath in June 2012 after taking to Twitter in to back an opponent of Segolene Royal in parliamentary elections.
She subsequently apologised for her comments, saying: "I had not yet realised that I was no longer a simple citizen." Francois Hollande's son Thomas said in the wake of the incident that he and his siblings no longer wanted to see their father's partner.
Francois Hollande has four children, now adults, with Segolene Royal, herself a prominent French politician. The pair met at a university party and were once French politics' power couple, both harbouring ambitions to be president of France.
Although they never married, the couple were together for about three decades, officially splitting up shortly after the 2007 presidential election.
Ms Royal was the Socialist candidate in that vote - the first woman in France to be nominated by a major party - but lost to Nicolas Sarkozy.
Mr Hollande has hit out at what he describes as an invasion of privacy, but has not denied a report that he is having a relationship with the actress Julie Gayet, a mother of two. The 41-year-old is fairly well known in France, if not internationally, and once appeared in one of Mr Hollande's election campaign television adverts.
In that video (in French), she described him as "a humble man," who "really listens".
Rumours of their alleged relationship have been circulating on the internet for many months. Ms Gayet filed a complaint with prosecutors in Paris in March 2013 against various bloggers and websites that were reporting on the rumours.
Gayet played a leading role in "Quai d'Orsay" a 2013 satirical film centred on the French foreign ministry. Her filmography also includes the titles "Shall We Kiss?" and "My Best Friend" among dozens of others.
Ms Gayet is the daughter of a wealthy surgeon and married the Argentine-born film director and scriptwriter Santiago Amigorena in 2003. The pair have since separated.
