A vegetarian excluded any meat-based foods from their diets, either as a personal choice or as part of their culture. They were not to be confused with herbivores, whose natural diet consisted solely of plant-based foods.

It was once noted by Spock that, as plants were living organisms, vegetarians and meat-eaters alike feed on death. (TOS: "Wolf in the Fold")

On early 21st century Earth, the term "Veggie" might be used for such a person. (ENT: "Carpenter Street")

A position related to Vegetarianism, Veganism, was indirectly referenced through vegan steak.


Most Vulcans, including T'Pol and Spock, were vegetarians. (ENT: "Broken Bow", "Terra Prime"; TOS: "All Our Yesterdays") The v'tosh ka'tur were a major exception, however. (ENT: "Fusion")

Spock was described as a herbivore once, in TAS: "The Slaver Weapon". In VOY: "Flashback", Tuvok eats (seemingly non-replicated) Porakan eggs. By some definitions, eggs are not vegetarian. The Vulcan propensity for vegetarianism was mentioned in the first draft script of ENT: "Shadows of P'Jem" (written while the episode had the working title "Untitled Andorians Return"), wherein Commander Tucker commented to Vulcan Captain Sopek, "For a bunch vegetarians, you people can be awfully trigger happy." In the final edit of the episode, the reference to vegetarianism is omitted, Tucker instead remarking to Sopek, "You're awfully trigger happy for someone who's repressed his emotions."


By 2364, Humans in the United Federation of Planets no longer enslaved animals for food purposes, although "meat" remained available, and continued to be eaten, in the form of the inorganically materialized output of replicators. An Antican ambassador, who insisted on slaughtering live animals for food, considered this practice to to be "sickening" and "barbaric." (TNG: "Lonely Among Us")

The inhabitants of Omicron Ceti III were forced to be vegetarians, after all the animals there died. (TOS: "This Side of Paradise")

The preference for keeping live animals by the Human colonists on Omicron Ceti III a century before the eradication of farming on Earth suggests the practice was abandoned sometime between those two points.

Commander Tucker once inquired if Colonel Grat was a vegetarian, during a dinner invite in 2152. (ENT: "Detained")

Some Humans, like Chakotay, also chose the life of a vegetarian as an expression of their spiritual beliefs (VOY: "Unity", "Workforce".)

Other species

The Trill Tobin Dax was also a vegetarian (DS9: "Afterimage").

Deanna Troi became concerned that the Evora may be vegetarians after they began eating the floral arrangements at their reception in 2375. (Star Trek: Insurrection)
