阿戈美拉汀（英语：Agomelatine） (商品名：维度新（Valdoxan）)是一种褪黑素受体激动剂类抗抑郁药，由法国施维雅（Servier）公司研制。阿戈美拉汀主要用来治疗重度抑郁症（MDD），并且证据指出阿戈美拉汀不会产生停药综合症和导致性功能障碍（对比SSRI、SNRI与三环类抗抑郁药）。 阿戈美拉汀对改善睡眠和认知也有积极的作用。

Agomelatine (BAN, rINN; trade names Valdoxan, Melitor, Thymanax) is a melatonergic antidepressant developed by the pharmaceutical company Servier. It is marketed for the treatment of major depressive disorder, primarily for its relatively favorable side effect profile: it avoids the weight gain, sexual dysfunction, and severe withdrawal associated with the most commonly-used classes of antidepressants (SSRIs, SNRIs, tricyclics), while providing similar therapeutic benefit.
