The Coneheads was a recurring sketch on Saturday Night Live (SNL) about a family of aliens with bald conical heads. It originated on the Saturday Night Live season 2, episode, and starred Dan Aykroyd as father Beldar, Jane Curtin as mother Prymaat, and Laraine Newman as daughter Connie. It was later made into Coneheads (film).

The Coneheads are an alien family, natives of the planet Remulak, who find themselves stranded on Earth. The Coneheads' most distinguishing feature is that, as their name implies, the tops of their heads are shaped like large cones. It is unclear if "Conehead" is the name of their race or just their surname, but in their interactions with humans, it is used in the latter sense.

When questioned by Earth neighbors as to their strange behavior, they invariably reply that they are from France, Remulak being the purported name of their home village. With the exception of Agent Seedling and his assistant in the 1993 feature-length version, they are never suspected of being extraterrestrial aliens by anyone who encounters them, even when accidentally referring to their neighbors as "Earthlings". Much of the humor is derived from this.

Coneheads have much larger appetites than an average human. They eat large amounts of food during meals, announcing "Consume mass quantities!" They drink entire six packsof beer at once, and smoke whole packs of cigarettes at a time. They also consume foods that are inedible to humans, including cleaning fluid, pencil shavings and insulation. On Halloween in 1977 (specifically, the October 29, 1977, SNL episode), a neighbor complains about the Coneheads' choice of trick-or-treat handouts: six-packs and fried eggs.

The Coneheads have a very fast, nasal, monotone speech and humorously strange language patterns, using needlessly technical dialogue. They refer to food as "consumables", and say "I summon you" to ask to speak to another person. The phrase, "Maintain low tones," is used towards Connie by Beldar in the film and in the original 1977 sketch. The somewhat popular term parental unit also comes from the sketches. When highly upset, some Coneheads emit the term, "Meps!"
