A lot of these bigger moments happen in the season finales, and as should be expected, some of these finales are better than others. These high-stakes episodes often serve as a culmination of character arcs and storylines, leaving fans on the edge of their seats. So, which ones are the best of the best in Grey’s Anatomy’s large catalogue of episodes? Let’s rank them, shall we?
10“All of Me” (2018)
Season 14, Episode 24
The Season 14 finale kicks off pretty happily and low-key with Alex (Justin Chambers) and Jo’s (Camilla Luddington) wedding. A lot of things go wrong, but nothing too drastic or devastating, just some simple bumps, such as them getting locked in a shed, and guests arriving at the wrong location. It’s more silly shenanigans that make their ultimate wedding feel all the more romantic and perfect by the end of the episode. It also saw sparks begin to fly between Meredith (Ellen Pompeo) and DeLuca (Giacomo Gianniotti).
9“Didn’t We Almost Have It All” (2007)
Season 3, Episode 25
Season 3 is another finale that had a fair bit going on. In terms of major events and tragedies, the stakes were low, but there was still plenty of drama and reveals. Adele (Loretta Devine) suffers a miscarriage, which is devastating to watch. Addison (Kate Walsh) leaves to start a new life in Los Angeles and lead her own spin-off titled Private Practice. And the end of the episode marks the arrival of Lexie Grey (Chyler Leigh), Meredith’s half sister, which set into motion a whole new area of the show.
8“Fear of the Unknown” (2014)
Season 10, Episode 24
The Season 10 finale bid adieu to one of Grey’s Anatomy’s most beloved, and longest-running characters: Cristina Yang. It was an exit that was brewing all season, but it didn’t make it any easier to say goodbye. Overall, Yang got the best send-off of any Grey’s Anatomy character. She left on her own terms for a bigger and better opportunity. There wasn’t any big tragedy or gnarly death that sealed her fate, just a final dance-it-out moment with Meredith and a tearful farewell from viewers.
7“Who’s Zoomin’ Who?” (2005)
Season 1, Episode 9
Season 1 of Grey’s Anatomy was relatively tame in comparison to the rest of the series, and honestly felt more like a comedy at times than the drama it became as it went on. But the Season 1 finale is the exact moment the show decided to pivot into the drama genre. After a whole season of will they or won’t they, Meredith and Derek (Patrick Dempsey) finally seemed to be ready to commit to each other no matter what their colleagues have to say about it.
Then the Season 1 finale came along, and with it one of the most memorable lines in the entire show. As Meredith and Derek are preparing to leave for the night, a woman approaches them, and Derek quickly apologizes before addressing the woman. She chides him for not answering her phone calls and then introduces herself as Addison Shepherd, and assumes Meredith to be “the woman who’s been screwing my husband.” Yep. McDreamy is married, which really brings the dreamy factor down a whole lot of notches. But it certainly amped up the drama for Season 2 and got fans excited.
6“Now or Never” (2009)
Season 5, Episode 24
Season 5 of Grey’s Anatomy was a big one because it was the first time someone other than Meredith was put at risk. Izzie (Katherine Heigl) discovers she has cancer, and it progresses throughout the season to the point where she starts preparing for the worst. She married Alex (Justin Chambers), and the pair even froze embryos together in hopes of getting a chance at a future together. In the Season 5 finale, that future looks grim, as Izzie’s health suddenly drops drastically, and she is left hanging in a sort of limbo at the end of the episode, with her fate unclear.
But on a much bigger note, the Season 5 finale said goodbye to George O’Malley (T.R. Knight) in one of the most tragic deaths in the show. A John Doe patient comes into the ER, horrifically disfigured after being hit by a bus and dragged for blocks. The man is barely clinging to life, but he musters enough strength to write on Meredith’s hand with his finger “007”, and Meredith’s cry of realization is haunting. It’s George. His nickname “007” was earned on his first day on the job. He succumbs to his injuries, giving Grey’s Anatomy its first main character death.
5“Ring of Fire” (2017)
Season 13, Episode 24
She saved a little girl from a dangerous predator who was also a patient at the time, and continued to protect her and get her out safely even after an explosion set the hospital aflame. The incident left Stephanie with horrible burns, but it’s an episode fans will never forget. It was also a memorable episode for revealing that Owen’s (Kevin McKidd) sister is alive. It’s a smaller reveal in comparison to Stephanie’s storyline, but it sets the stage for a bigger arc in the following season.
4“Perfect Storm” (2013)
Season 9, Episode 24
But the most memorable moment to come from this finale, by a landslide, is everything to do with Callie and Arizona. Arizona sleeps with a visiting doctor named Lauren Boswell (Hilarie Burton), and Callie finds out, which naturally leads to the deterioration of Callie and Arizona’s marriage. It had been on the fritz since the plane crash and Mark’s (Eric Dane) death, but this was the final nail in the coffin and really sealed their fate.
3“Flight” (2012)
Season 8, Episode 24
The plane crash in Season 8 is one of the most memorable moments in Grey’s Anatomy history. Not only did it take the doctors out of the hospital and drop them into the middle of nowhere, but it also took out some major characters and left others with lasting impacts. Derek suffers a hand injury that nearly ends his career as a surgeon. Arizona gets a leg injury so bad that she has to get it amputated when they return home (this also leads to problems between her and Callie). And Cristina suffered from PTSD afterward and refused to speak or let anyone touch her while she was a patient.
2“Death and All His Friends” (2010)
Season 6, Episode 24
Few episodes have shaken up a fan base as much as the hospital shooting episode in Grey’s Anatomy. After the distraught widow of a patient comes into the hospital armed and looking for Derek, he decides to take multiple casualties on his way. You don’t see it coming at first, until he approaches Reed (Nora Zehetner) and shoots her point-blank. Suddenly the entire tone of the show shifts. It’s not just a medical drama anymore; it’s a terrifying thriller. There are a lot of major injuries and casualties in this episode. For starters, Alex gets shot and is nursed back to health by Lexie and Mark. Charles Percy (Robert Baker) dies in Bailey’s (Chandra Wilson) arms, and Bailey herself is very nearly added to the body count.
1“Losing My Religion” (2006)
Season 2, Episode 27
There’s truly no other option for the number one spot other than the Season 2 finale. While so many of the show’s season finales are memorable, Season 2 is specifically one that sticks with viewers. It features the hospital prom, during which Meredith and Derek hook up despite him being with Addison. The aftermath of this decision results in Addison finding Meredith’s underwear in Derek’s coat pocket and pinning it to a corkboard for everyone in the hospital to see.
