Octagon buildings and structures are characterized by an octagonal plan form, whether a perfect geometric octagon or a regular eight-sided polygon with approximately equal sides.

The oldest known octagon-shaped building[citation needed] is the Tower of the Winds in Athens, Greece, which was constructed circa 300 B.C. Octagon houses were popularized in the United States in the mid-19th century and there are too many to list here, see instead List of octagon houses. There are also octagonal houses built in other times and cultures.

Below is a list of octagonal buildings and structures worldwide, excluding houses and windmills.

This included octagonal deadhouses, pre-burial edifices, built in the mid to late 1800s along Yonge Street in south-central Ontario, from just north of Toronto to Aurora.
