二氯二茂钛（英语：Titanocene dichloride）是一种化学式为(η-C₅H₅)₂TiCl₂的有机钛化合物，常写为Cp₂TiCl₂。这种茂金属是有机金属化学与有机合成中的常用试剂。其性质为亮红色固体，在空气中会缓慢的水解。Cp₂TiCl₂并不会形成二茂铁那样的“三明治”结构，由于其4个配体围绕一个金属中心，会形成一个四面体结构。由于其具有一定的抗肿瘤活性，已经作为化疗药物进入临床试验。

Titanocene dichloride is the organotitanium compound with the formula (η-C₅H₅)₂TiCl₂, commonly abbreviated as Cp₂TiCl₂. This metallocene is a common reagent in organometallic and organic synthesis. It exists as a bright red solid that slowly hydrolyzes in air. Cp₂TiCl₂ does not adopt the typical "sandwich" structure like ferrocene due to the 4 ligands around the metal centre, but rather takes on a distorted tetrahedral shape. It shows antitumour activity and was the first non-platinum complex to undergo clinical trials as a chemotherapy drug.
