What Kind of Star Trek Information Can I Find on Memory Alpha?
Memory Alpha is an English-language, collaborative Star Trek encyclopedia that has been running since November 2003 and currently holds 66,575 articles and 71,420 files. If you want Star Trek information, it is a reference wiki rather than a streaming service or news outlet, so you go there to read up on episodes, characters, production details, and in-universe concepts — and you should expect spoilers, since the site carries an explicit spoiler warning.
Episode and series coverage
The wiki maintains entries for Star Trek productions, including current series. Its front page tracks Star Trek: Strange New Worlds across Seasons 1 through 5, listing episode titles such as "Once La'An a Time" and "Tomorrow's Enterprise" alongside air dates (17 September 2026 and 24 September 2026, with 2027 entries also noted). It also links to aftershow and special coverage, such as The Ready Room and Strange New Worlds specials for Seasons 4 and 5.
Use this if you want to confirm an episode title, check when something aired, or see how a season's episodes are organized.
Characters and cast
Character pages are a core part of the wiki. The Strange New Worlds section alone links to figures such as Christopher Pike, Spock, Una Chin-Riley, James T. Kirk, Nyota Uhura, Montgomery Scott, Christine Chapel, Joseph M'Benga, Erica Ortegas, La'An Noonien-Singh, Gary Mitchell, and Phil Boyce. Casting news is also recorded — for example, the site notes that SNW Season 5 will add Thomas Jane as Dr. Leonard McCoy and Kai Murakami as Hikaru Sulu.
This is the place to look when you want to know who a character is, who plays them, or when a casting change was announced.
In-universe concepts and terminology
Memory Alpha explains setting and terminology, not just people and episodes. The featured article on the front page covers the IKS Rotarran, a Klingon Bird-of-Prey in service during the 2370s, and describes the Klingon fleet's withdrawal from Cardassian space in mid-2373 after Cardassia joined the Dominion. The Strange New Worlds section also links to concepts like black holes and white holes.
Turn here when a term, ship, or species comes up in an episode and you want a definition tied back to specific story events.
News, featured articles, and "Today in Trek history"
Beyond reference entries, the site runs several recurring sections:
- Latest news — award nominations and franchise announcements, such as Strange New Worlds, Holly Hunter, and Paul Giamatti receiving Critics Choice Super Awards nominations (15 July 2026), Star Trek receiving the inaugural "Franchise of the Year" award from the Broadcasting+Cable Hall of Fame (announced 7 April 2026, awarded 29 September 2026), Saturn Awards nominations, and a MUAHS Guild Award nomination for Star Trek: Section 31.
- Featured article — a rotating in-depth entry, currently the IKS Rotarran.
- Today in Trek history — a daily historical note.
- In memoriam — recent deaths, such as Gerrit Graham, Leslie Parrish, and Kelly Curtis.
- Upcoming releases and Where to watch — pointers to what is coming and where to find it.
Practical notes before you use it
- Language: The English Memory Alpha is the largest edition, but the site links to many other language versions, including Deutsch, Español, Français, 日本語, Русский, and 中文.
- Spoilers: The site warns that it contains spoilers, so avoid it if you are not caught up on a series.
- Editing: It is a collaborative project, so pages can be edited and may change over time; treat it as a community reference rather than an official studio source.
- Not a viewing service: Nothing on the front page indicates streaming or paid access — it is an information resource, and "Where to watch" is a pointer rather than a player.
If your goal is to look up a specific episode, character, ship, or term, start with the search box; if you want to browse, the series portals and featured article are the fastest entry points.
