铃木（すずき）反应（Suzuki reaction），也称作铃木（すずき）偶联反应（Suzuki coupling）、铃木（すずき）－宫浦（みやうら）反应（Suzuki-Miyaura reaction），是一个较新的有机偶联反应，是在钯配合物催化下，芳基或烯基的硼酸或硼酸酯与氯、溴、碘代芳烃或烯烃发生交叉偶联。

该反应由铃木章（日语：铃木 章／すずき あきら）在1979年首先报道，在有机合成中的用途很广，具有很强的底物适应性及官能团耐受性，常用于合成多烯烃、苯乙烯和联苯的衍生物，从而应用于众多天然产物、有机材料的合成中。铃木章也凭借此贡献与理乍得·赫克、根岸英一共同获得2010年诺贝尔化学奖。

The Suzuki reaction is the organic reaction that is classified as a coupling reaction where the coupling partners are a boronic acid with a halide catalyzed by a palladium(0) complex. It was first published in 1979 by Akira Suzuki and he shared the 2010 Nobel Prize in Chemistry with Richard F. Heck and Ei-ichi Negishi for their effort for discovery and development of palladium-catalyzed cross couplings in organic synthesis. In many publications this reaction also goes by the name Suzuki–Miyaura reaction and is also referred to as the "Suzuki Coupling". It is widely used to synthesize poly-olefins, styrenes, and substituted biphenyls. Several reviews have been published describing advancements and the development of the Suzuki Reaction. The general scheme for the Suzuki reaction is shown below where a carbon-carbon single bond is formed by coupling a organoboron species (R₁-BY₂) with a halide (R₂-X) using a palladium catalyst and a base.
