Khaki is a color, a light shade of yellow-brown similar to tan or beige. Khaki is a loanword incorporated from Hindustani and Urdu (both meaning "soil-colored") and is originally derived from the Persian: (khâk, literally meaning "soil"), which came to English from British India via the British Indian Army. It has been used by many armies around the world for uniforms, including camouflage. It has been used as a color name in English since 1848.

However, the name is sometimes also used to describe a drab green color. In the mid-twentieth century as many Western militaries adopted an olive drab instead of the older, more brownish khaki, the two color names became associated with each other. In French, and German, for example, "khaki" refers to a much darker olive drab-style military green.

The color shown at left matches the color designated as khaki in the 1930 book "A Dictionary of Color," the standard for color nomenclature before the introduction of computes.
