依赖型人格障碍（英语：dependent personality disorder，缩写为DPD），旧称无力型人格障碍，是以心理上的过分依赖他人为特征的一种人格障碍。这种人格障碍的状况是长期存在的（慢性的）。罹患依赖型人格障碍的人会依赖于他人以满足自己情感需求和生理需求，只有少数的人可以达到正常的独立水平。

“依赖性人格”和“依赖型人格障碍”的区别是有几分主观色彩的，这也使对其的诊断需要对文化影响因素（比如性别角色期望）十分敏感。

2012年的一个研究发现2/3的依赖型人格障碍患者的病因为遗传因素而1/3的患者则源于环境因素。

Dependent personality disorder (DPD), formerly known as asthenic personality disorder, is a personality disorder that is characterized by a pervasive psychological dependence on other people. This personality disorder is a long-term (chronic) condition in which people depend on others to meet their emotional and physical needs, with only a minority achieving normal levels of independence.
