血管紧张素（Angiotensin），亦称血管收缩素、血管张力素，是一种寡肽类激素，是肾素-血管紧张素系统（renin-angiotensin system）的重要组成部分。血管紧张素能引起血管收缩，升高血压；促进肾上腺皮质释放醛固酮。它也具有很强的致渴作用。血管紧张素的前体是由肝脏合成的一种血清球蛋白：血管紧张素原。血管紧张素最早于20世纪30年代末由美国印第安纳和阿根廷的研究人员分别独立分离，并被分别命名为Angiotonin和Hypertensin，后来被美国克利夫兰诊所和瑞士巴塞尔的汽巴实验室（Ciba Laboratories）描述并合成。

Angiotensin is a peptide hormone that causes vasoconstriction and a subsequent increase in blood pressure. It is part of the renin-angiotensin system, which is a major target for drugs that lower blood pressure. Angiotensin also stimulates the release of aldosterone, another hormone, from the adrenal cortex. Aldosterone promotes sodium retention in the distal nephron, in the kidney, which also drives blood pressure up.
