A heptagon is a seven-sided polygon. It is also sometimes called a septagon, though this usage mixes a Latin prefix sept- (derived from septua-, meaning "seven") with the Greek suffix -gon (from gonia, meaning "angle"), and is therefore not recommended.

A heptagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular heptagon.
