腹侧被盖区（英语：Ventral tegmental area，简写为VTA）是中脑的一个区域。这个区域靠近黑质与红核，富含多巴胺与5-羟色胺神经元，是两条主要的多巴胺神经信道的一部份：

科学家认为腹侧被盖区是愉悦系统或是报偿回路（reward circuit，奖励作用与行为刺激的主要来源）的一部分。当一个行动产生愉悦的时候，能够刺激腹侧被盖区；另外中枢神经兴奋剂（psychostimulant，例如古柯碱）也能直接刺激这个区域。因此腹侧被盖区被认为与神经生物学理论中的成瘾现象有关。

同时腹侧被盖区也处理许多种情绪与安全感，因此可能与回避作用（avoidance）及恐惧制约（fear-conditioning）有关。

The ventral tegmental area (VTA), (tegmentum is Latin for covering), also known as the ventral tegmental area of Tsai, or simply ventral tegmentum, is a group of neurons located close to the midline on the floor of the midbrain (mesencephalon). The VTA is the origin of the dopaminergic cell bodies of the mesocorticolimbic dopamine system and is widely implicated in the drug and natural reward circuitry of the brain. It is important in cognition, motivation, orgasm, drug addiction, intense emotions relating to love, and several psychiatric disorders. The VTA contains neurons that project to numerous areas of the brain, from the prefrontal cortex (PFC) to the caudal brainstem and several regions in between.
