Sa heometriya, an heptagono (Ingles: heptagon) iyo sarong poligono na may pitong gilid o 7-gon.

An heptagono iyo minsan naaapod bilang an septagono (septagon), gamit an "sept-" (sarong pagtangkas sa septua-, naderiba sa Latin na prepiksong numerikal, imbes na hepta-, naderiba sa Griyegong prepiksong numerikal; relatibo an parehas) kaiba an Griyegong supikso na "-agon" na may boot-sabihon na angulo.
