Under the Whyte notation for the classification of steam locomotives, a 2-2-2 locomotive has two leading wheels, two driving wheels and two trailing wheels. This type was named Jenny Lind, after Jenny Lind, a popular early 2-2-2 design, and sometimes Single, although that name more commonly means any kind of locomotive with a single pair of driving wheels.

Other equivalent classifications are:
UIC classification: 1A1 (also known as German classification and Italian classification)
French classification: 111
Turkish classification: 13
Swiss classification: 1/3

In the UK some 2-2-2s were made by James Holden as a result of his experiments removing the side rod from a 2-4-0.
