The Rhaetian Railway Ge 4/4 ^I is a class of metre gauge Bo′Bo′ electric locomotives operated by the Rhaetian Railway (RhB), which is the main railway network in the Canton of Graubünden, Switzerland.

The class is so named because it was the first class of locomotives of the Swiss locomotive and railcar classification type Ge 4/4 to be acquired by the Rhaetian Railway. According to that type designation, Ge 4/4 denotes a narrow gauge electric adhesion locomotive with a total of four axles, all of which are drive axles.

The 10 machines in the Ge 4/4 ^I class were also the first RhB electric locomotives without rod drive.
