The ST connector is a fiber optic connector which uses a plug and socket which is locked in place with a half-twist bayonet lock.

The ST connector was the first defactor standard for fiber optic cabling.

The ST connector has been standardized as FOCIS 2 (Fiber Optic Connector Intermateability Standards) in EIA/TIA-604-02.
