The 100 (pronounced The Hundred ) is an American post-apocalyptic drama television series that premiered on The CW during the 2013–14 American television season. The series is based on a book of the same name, the first in a series by Kass Morgan, and developed by Jason Rothenberg. The show premiered on Wednesday, March 19, 2014.

The following is a list of characters that have appeared on the television series. Although some are named for, or based upon characters from Kass Morgan's The 100 series, there are others created solely for the television series.

Sky people (Also known as arkers, or skaikru in Trigedasleng) is a term used by the grounders to describe a person who came from the international space station known as The Ark. The sky people alive today are descendants of humans who survived the nuclear apocalypse 97 years before the show by living in space in the Ark. Within the sky people community, there is a subgroup known as The 100 (also known as the delinquents), a term used to describe one hundred juvenile delinquents who, after it became clear that the Ark was dying, were sent to Earth in order to determine if the planet had become habitable enough for the rest of the sky people to survive in exchange for being pardoned of their crimes. However, the name "The 100" is slightly a misnomer, since, along with the aforementioned hundred delinquents, there were also two additional young adults who came with them to Earth; one was a security guard who sneaked aboard their ship to ensure the safety of his sister, and the other was a young engineer who came down to Earth in a pod shortly afterward to reassure the council that the delinquents survived their journey.

The "grounders" (or "outsiders," as they are known by the mountain men or tricru) is a term to describe a group of people who were born on Earth rather than in space or in Mount Weather. The grounders alive today are descendants of humans who survived the nuclear apocalypse 97 years ago due to their enhanced tolerance to nuclear radiation. Many of the sky people have negative views toward grounders, who they see as barbaric stone-age savages, just like a lot of grounders have a negative view of The 100, who they see as selfish colonizers, though relations between the two groups are slowly improving over time. The grounders speak a language called 'Trigedasleng' which is a composite of various old and modern languages merged into one, although some of them have a knowledge of English. Grounders were the primary antagonists of the first season. There are at least twelve grounder clans on Earth, including the woods clan (also known as the tree people, or trikru in Trigedasleng), ice nation (also known as Azgeda or Azgedakru in Trigedasleng), and the boat people (also known as Floukru or Floudon kru in Trigedasleng).
