French Sign Language (French: langue des signes française, LSF) is the sign language of the deaf in France and French-speaking parts of Switzerland. According to Ethnologue, it has 100,000 native signers.

French Sign Language is related and partially ancestral to Dutch Sign Language (NGT), Flemish Sign Language (VGT), Belgian-French Sign Language (LSFB), Irish Sign Language (ISL), American Sign Language (ASL), Quebec (also known as French Canadian) Sign Language (LSQ), Brazilian Sign Language (LSB, LGB or LSCB) and Russian Sign Language (RSL).
