CXXII is the Roman numeral for the number 122. It is formed by combining the symbols C (100), XX (20), and II (2), yielding 100 + 20 + 2. In standard Roman numeral notation, numbers are read from left to right, adding the values of the symbols. The subtractive principle is used for specific pairs such as IV (4) or XC (90), but 122 is written additively as CXXII.

Historically, CXXII appears in contexts where Roman numerals are used to denote numbers, such as dates, chapter or section numbers, and enumerations in Latin texts. Although the form is ancient, it remains in occasional use in modern contexts for stylistic or traditional purposes, including outlines, monuments, or decorative inscriptions. In these settings, CXXII serves the same numeric function as any other representation of 122.

In practice, CXXII is primarily a representation of the integer 122 within the broader system of Roman numerals. It is distinct from other numerals that denote nearby values (for example, CXII for 112 or CXXIII for 123) and illustrates the additive approach characteristic of Roman numerals, where larger values are placed before smaller ones without invoking subtraction. Beyond numerical use, CXXII may appear as a designation in various model names, catalog numbers, or symbolic inscriptions where Roman numerals are preferred.
