thumb|A whole regular chiliagon is not visually discernible from a circle. The lower section is a portion of a regular chiliagon, 200 times as large as the smaller one, with the vertices highlighted. In geometry, a chiliagon () or 1,000-gon is a polygon with 1,000 sides. Philosophers have used chiliagons to illustrate ideas about the nature and workings of thought, meaning, and mental representation.

== Regular chiliagon== A regular chiliagon is represented by Schläfli symbol {1,000} and can be constructed as a truncated 500-gon, t{500}, or a twice-truncated 250-gon, tt{250}, or a thrice-truncated 125-gon, ttt{125}.
