去氧鸟苷二磷酸（Deoxyguanosine diphosphate；dGDP）是较为常见的核酸GTP之衍生物，比GTP少了一个位在五碳糖2号碳上的-OH基，含有两个磷酸基团。

Deoxyguanosine diphosphate (dGDP) is a nucleoside diphosphate. It is related to the common nucleic acid guanosine triphosphate (GTP), with the -OH group on the 2' carbon on the nucleotide's pentose removed (hence the deoxy- part of the name), and with one fewer phosphoryl group than GTP.
