A tick (known as a check mark or check in American English) is a mark (✓, ✔, ☑, etc.) used to indicate the concept "yes", for example "yes; this has been verified" or, "yes; that is the correct answer". Its opposite is the x mark, although the x mark can also be positive (most notably on election ballot papers).

As a verb, to tick (off) or to check (off) means to add such a mark. It is quite common, especially on printed forms, printed documents, and computers (see check box), for there to be squares in which to place ticks.

In some European countries^{[citation needed]} (e.g., Finland and Sweden), the tick can be used as an error mark and indicates "no" rather than "yes". In Japan, an "O Mark" (in the appearance of a circle, Unicode symbol "◯"), also known as "丸印" marujirushi, is used instead of a tick to mean "yes"; this symbol is also used in Korea.

A rainbow-colored tick was also used for the Amiga logo during the Commodore era of the Amiga (1985–1994).
