Comité International des Sports des Sourds (CISS) is the apex body organizing international sports events for the deaf, particularly the Deaflympics (previously called World Games for the Deaf). It is also called the International Committee of Sports for the Deaf.
The organization was founded in Paris by Eugène Rubens-Alcais, who organized the first "International Silent Games" in 1924. Alcais was himself deaf and was the president of the French Deaf Sports Federation.
CISS, now also called ICSD, is presently headquartered in Maryland, USA.
