The tetradecagram, or tedag, is a non-convex polygon with 14 sides. It is the second stellation of a tetradecagon. A regular tetradecagram has equal sides and equal angles.

It is one of two regular 14-sided star polygons in 2D, the other being the great tetradecagram.

It is the uniform truncation of the great heptagram.
