When I finished watching the original Star Trek series, I posted a ranked list of all the episodes. However, I don’t think ranked lists are the most effective way to show the best of a TV series. So for Star Trek: The Next Generation, I’m making an essential viewing guide. This list includes all of the episodes that I gave a grade of A- or higher, but also significant episodes to ongoing story and character arcs throughout the series. Mind you, these aren’t the only episodes you should watch if you’re interested in Star Trek: The Next Generation, but they are the episodes I think you shouldn’t miss. 72 of the series 178 episodes are listed here, but if you think I overlooked any vital episodes, let me know in the comments.
Season 1
- 1-2. Encounter at Farpoint – the premiere is stiff and uneven, but it introduces all our main characters as well as Q.
- 6. Where No One Has Gone Before – the first truly good adventure for the Enterprise-D, which introduces the Traveler and a story arc for Wesley Crusher.
- 12. The Big Goodbye – the first of many stories in which the holodeck goes wrong, and one of the best.
- 13. Datalore – gets us acquainted with Data’s origin story and introduces his evil twin.
- 20. Heart of Glory – an introduction on how The Next Generation is going to explore Klingon culture in ways never seen before and Worf’s ongoing efforts to learn about his people.
- 23. Skin of Evil – typically, killing off a major character in the first season is a bold move, but for TNG it was a sign of the series’ production troubles. Nevertheless, Tasha Yar’s memorial service may be the character’s best moment.
Season 2
- 3. Elementary, Dear Data – Data & Geordi’s fascination with Sherlock Holmes stories accidentally leads to the creation of an AI lifeform.
- 8. A Matter of Honor – Riker joins a Klingon ship on an officer exchange program. More Klingon fun and a great episode for Riker.

- 16. Q Who – The crew of the Enterprise-D face their most notorious adversary for the first time, the Borg!
- 20. The Emissary – In order to negotiate with a Klingon sleeper ship, the Federation sends half-Klingon/half-human K’Ehleyr to join the Enterprise, who turns out to be a romantic interest for Worf. An important story in Worf’s ongoing character arc.
- 21. Peak Performance – to prepare for the Borg, the Enterprise crew are split into two ships to compete in military exercises. A good episode for the characters showing their talents outside of their typical roles.
Season 3
- 5. The Bonding – Worf bonds with a boy orphaned after his mother dies on away mission. Ronald D. Moore’s first script for the show.
- 6. Booby Trap – Geordi figures out how to fix the warp drive with a holodeck recreation of its designer, Dr. Leah Brahams and Picard shows off his piloting skills.
- 7. The Enemy – Geordi is stranded on a planet with a Romulan crash survivor and they have to work together to escape.
- 10. The Defector – An elite Romulan defects to the Federation in an effort to prevent war. But does his story ring true?
- 13. Deja Q – Q is stripped of his powers and forced to live as a human in this humorous episode.
- 15. Yesterday’s Enterprise – a time rift creates an alternate timeline where the Federation is at war with the Klingon Empire and Tasha Yar is still alive. An all-time classic!

- 22. The Most Toys – Data is captured by a collector and put in a private museum, but stoically refuses to be treated as an object. A great performance by Brent Spiner.

- 26. The Best of Both Worlds, Part 1 – the Borg are preparing to attack Earth and they assimilate Picard to be their mouthpiece. This was the first season-ending cliffhanger for Star Trek and one of the best.

- 8. Future Imperfect – Riker wakes up 16 years in the future not remembering what happened in the intervening years.
- 11. Data’s Day – A concept episode that shows one day from the point of view of Data. It’s also a story that’s key for Keiko and Miles O’Brien, and introduces Data’s cat Spot!

- 14. Conundrum – the entire crew lose their memory and have to figure out who is in charge and what is their mission.
- 17. The Outcast – in a story that acts as a metaphor for the LGBTQ experience, Riker and a person from an androgynous society fall in love.
- 18. Cause and Effect – a great time loop story that features the Enterprise exploding several times and then meeting Kelsey Grammer.
- 19. The First Duty – Wesley Crusher is caught up in a scandal at Starfleet Academy.
- 23. I, Borg – a Borg separated from the hive mind begins to develop an individual personality and takes on the name Hugh.

Season 6
- 4. Relics – Scotty is back after being trapped in a transporter for decades. After some fan service, the show depicts Scotty finding a way to feel useful working with Geordi.

- 21. Frame of Mind – Riker is made to believe that he’s in a mental institution and everything he knows about his life is a delusion. Great performance by Jonathan Frakes.

- 25. Timescape – Picard, Troi, LaForge, and Data return from a conference to find the Enterprise frozen in time while trapped in a battle with a Romulan warbird. A fun mystery ensues.

- 20. Journey’s End – an awkward story in which the removal of a settlement of Native Americans on a planet now in Cardassian territory. The episode is important because it ends Wesley Crusher’s story arc with The Traveler, and introduces the background to the Maquis, who will play a greater role in Deep Space Nine and Voyager.
- 24. Preemptive Strike – speaking of the Maquis, Ro Laren is assigned to infiltrated a cell and finds herself sympathetic to their cause.
- 25-26. All Good Things… – the journey comes full circle as Picard finds himself jumping in time to 7 years earlier and into the far future. Naturally, Q is involved.
