Police in Paris are expecting up to 300,000 protesters to march through the city protesting against the legalisation of same sex marriages.
The protest is aimed against President Francois Hollande's proposals to legalise same sex marriage, as well as allowing same sex couples the right to adopt.
On Tuesday, the President met with local religious leaders, including the country's chief Rabbi to discuss the issue of gay marriage, and to hear out their opinions on the matter.
Support for gay marriage in France has sharply dropped, from 65 percent in favour, to around 50 percent being in favour now.
The French capital was the scene of another large protest related to this issue just last month, with a large number of protesters rallying in support of same sex marriages, and the right for same sex couples to adopt.
