In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, "eight angles") is an 8-sided polygon or 8-gon.

Juan Escalera (born March 27, 1961) is a Mexican luchador enmascarado (masked professional wrestler) better known as Octagón. He is best known for working for Asistencia Asesoría y Administración (AAA), having worked for the company since it was founded in 1992. In 2011 he was inducted into the promotion's Hall of Fame. Octagón formed a tag team with El Hijo Del Santo to take on Los Gringos Locos (Eddie Guerrero and Art Barr) in a double mask versus hair match on the first pay-per-view put on by a Mexican wrestling promotion to air in the United States. Over the years the Octagón gimmick has spawned a Mascot called Octagoncito and an "Evil clone" known as Pentagón. In 2014, Escalera quit AAA.
