In organic chemistry, a Hiyama coupling is a palladium-catalyzed cross-coupling reaction of organosilanes with organic halides or triflates. Hiyama couplings were first reported by Yasuo Hatanaka and Tamejiro Hiyama in 1988.

Typically, the Hiyama coupling reaction is promoted by activation of the organosilane with fluorides. The reaction possesses many advantages such as low environmental impact, high atom efficiency, and easy handling compared with the coupling reactions of organoboron, organozinc, or organotin compounds.
