Vulcans, sometimes referred to as Vulcanians, are a fictional extraterrestrial humanoid species in the Star Trek universe and media franchise. In the various Star Trek television series and films, they are noted for their attempt to live by logic and reason with as little interference from emotion as possible. Known for their pronounced eyebrows and pointed ears, they originate from the fictional planet Vulcan. In the Star Trek universe, they were the first extraterrestrial species to make contact with humans.

Pointy ears or pointed ears are a characteristic of many animals, a genetic disorder in humans, as well as a cliché in popular culture, particularly in the fantasy genre. They are commonly known as "elf ears".
