The 20-year-old, who came through the youth system at Lyon after they took him on in 2010, signed a three-year deal.
Nganioni, capped seven times at Under-20 level, played in several friendly pre-season matches last year but has yet to play in Ligue 1.
Nganioni's decision to remain with Lyon comes on the heels of last season's title runners-up completing the signing of Guingamp's freescoring forward Claudio Beauvue on Thursday.
They had previously strengthened their defence with the signing of the experienced fullback Jeremy Morel from Marseille.
