A connecting rod for a piston engine, in particular a twin crankshaft piston engine, with a first connecting rod head (2) that comprises a first connecting rod eye (20) for mounting a connecting rod (1) to a piston (52) of the piston engine. A second connecting rod head (3) has a second connecting rod eye (30) for mounting the connecting rod (1) to the crankpin (58; 59) of a crankshaft (60; 61) of the piston engine, along with a connecting rod shank (4) that links the first connecting rod head (2) and the second connecting rod head (3). The connecting rod shank (4) has a narrow first connecting rod shank section (40) adjacent to the first connecting rod head (4) and the connecting rod shank (4) includes a wider second connecting rod shank section (45) adjacent to the second connecting rod head (3). The first connecting rod shank section (40) and the second connecting rod shank section (45) merge with one another in a step-like manner and the narrow first connecting rod shank section (40) is narrower in the region in which it merges with the first connecting rod head (2) than the exterior diameter (D) of the first connecting rod head (2).
