在解剖学中，淋巴管（Lymph vessels 或 lymphatic vessels），是指构成淋巴系统的一部分，能让淋巴流动的管道，其构造类似静脉，与上大静脉连接，负责运送内含有蛋白质、脂肪，以及B淋巴细胞与T淋巴细胞，呈乳状的淋巴液。

在过去，医学界认为淋巴管不存在于大脑之中，也以此指导学生；不过到了2014年10月，一群维吉尼亚医护大学的学者们，在中枢神经系统里也发现了淋巴管的存在。这是由Antoine Louveau博士在研究小老鼠脑部结构时首先发现的，与其他人的近一步共同研究论文，已被刊载在2015年6月的《自然》期刊。而这项发现除了将改写数十年的教科书以外，也将为治疗阿兹海默症、自闭症、多发性硬化症等与免疫系统或中枢神经系统有关的病症，带来巨大影响。

In anatomy, lymphatic vessels or lymph vessels are thin walled, valved structures that carry lymph. As part of the lymphatic system, lymph vessels are complementary to the cardiovascular system. Lymph vessels are lined by endothelial cells, and have a thin layer of smooth muscles, and adventitia that bind the lymph vessels to the surrounding tissue. Lymph vessels are devoted to propulsion of the lymph from the lymph capillaries, which are mainly concerned with absorption of interstitial fluid from the tissues. Lymph capillaries are slightly larger than their counterpart capillaries of the vascular system. Lymph vessels that carry lymph to a lymph node are called the afferent lymph vessel, and one that carries it from a lymph node is called the efferent lymph vessel, from where the lymph may travel to another lymph node, may be returned to a vein, or may travel to a larger lymph duct. Lymph ducts drain the lymph into one of the subclavian veins and thus return it to general circulation.
