Tom Clancy's Jack Ryan (also known simply as Jack Ryan) is an American political action thriller television series, based on characters from the fictional "Ryanverse" created by Tom Clancy, that premiered on August 31, 2018, on Amazon Prime Video. The series was created by Carlton Cuse and Graham Roland. Cuse serves as an executive producer alongside John Krasinski, Michael Bay, and Mace Neufeld, among others. Krasinski also stars in the series as the title character.
 Ahead of the third season, Amazon renewed the series for a fourth season and in May 2022, it was confirmed the series would end after its fourth season, which premiered on June 29, 2023 and concluded on July 14. A spin-off starring Michael Peña as Ding Chavez is in development.
 The first season follows the titular CIA analyst as he is wrenched from the security of his desk job into the field after discovering a string of dubious bank transfers, which are being carried out by a rising Islamic extremist named Suleiman. 
 The second season sees Jack in the middle of political warfare in a corrupt Venezuela.
 In the third season, Jack investigates a plot to re-create the former Soviet Union by detonating an untraceable tactical nuclear bomb in a country of former Eastern Bloc.
 In the fourth season, Jack, now the CIA's acting deputy director, will face his most dangerous mission yet, which involves a foe operating both in the United States and further afield.  The trouble begins after he begins investigating rumours of internal corruption, during which he and his trusted associates uncover evidence of an alliance between a drug cartel and a terrorist organization.
 On September 22, 2015, it was announced that Carlton Cuse and Graham Roland were developing a television series adaptation of Tom Clancy's Jack Ryan series of novels.

On May 9, 2022, before the release of the third season, it was confirmed the series would end after the fourth season, which premiered on June 30, 2023.

 On Rotten Tomatoes it received an overall score of 77%, and an overall score of 67 on Metacritic.
 The series premiered to a positive critical response. On the review aggregation website Rotten Tomatoes, the first season holds an approval rating of 75% with an average rating of 6.4 out of 10, based on 85 reviews. The site's critical consensus reads: "Though not as thematically rich as some of its geopolitical predecessors, Jack Ryan is a satisfying addition to the genre buoyed by exceptional action sequences and a likable cast." Metacritic, which uses a weighted average, assigned the season a score of 66 out of 100 based on 28 critics, indicating "generally favorable reviews".
 In a positive review, RogerEbert.com's Nick Allen praised the series saying, "Expertly plotted by creators Carlton Cuse and Graham Roland, Tom Clancy's Jack Ryan is all the more impactful for its restraint and scope, offering excellent character-based drama that's concerned with much more than just its namesake." Similarly favorable, The Gazette's Terry Terrones awarded the series a grade of "A−" and directed specific approval towards Krasinski's performance saying, "This version of Jack Ryan is relatable, but also admirable because the actor portraying him can balance so many aspects of the character with ease. Krasinski plays him so naturally I couldn't tell where he ended and Ryan began." In another enthusiastic appraisal, Rolling Stone's Alan Sepinwall accorded the series three and a half stars out of five and complimented it saying, "Like Jack Ryan himself, the Amazon show is smart and confident and thorough. That's enough to get the job done."
 In a more mixed assessment, TVLine's Dave Nemetz gave the series a grade of "C+" and offered the series restrained commendation saying, "Amazon's awkwardly titled Tom Clancy's Jack Ryan is at its best when things are exploding, delivering a number of impressively high-octane action sequences on a scale rarely seen on television. The rest of the series, though, is disappointingly mediocre ... and its choice of leading man may be a major stumbling block." In a negative critique, Vanity Fair's Sonia Saraiya chastised the show saying "Tom Clancy's Jack Ryan is hysterical. Hysterical as in histrionic; hysterical as in somehow funny; hysterical as in you wish its team had worked harder to take the temperature of the world around us before sending this highly charged and obscenely blinkered James Bond manqué into the world." Equally dismissive, Paste's Amy Amatangelo criticized the series saying, "But more often than not, the show plods along with no real sense of urgency. I often had to restrain myself from scrolling through my phone. I was that bored while I was watching. Those indoctrinated into the Jack Ryan canon via the books or the movies will find the eight-episode series is faithful to the spirit of all that preceded it. I'm just not sure we needed it at all."
 The series has been criticized for a scene in the episode "Black 22" in which a character uses the word tranny. LGBT activist Eliel Cruz alleged that the scene treats a major cause of violence against trans women as "a throwaway joke." Similarly, the series has also received criticism in French publications for its depiction of the country, specifically in the episodes "French Connection" and "Black 22", where various scenes have been condemned. Stéphanie Guerrin of Le Parisien expressed her concern for the dialogue spoken by and about the French saying, "This series of dangerously caricatural comments leaves one wondering." Le Point's Bastien Haugel specifically took grievance, in an otherwise positive review, with the portrayal of a French policeman who espoused anti-Muslim views calling it "dangerously caricatural".
 Previews of season two, in which Ryan ends up on a mission to Venezuela to "bring stability to a country on the brink of collapse", has been criticized by the government of Venezuela for allegedly promoting an invasion of the country by the United States. Venezuela's Minister of Cultural Affairs, Ernesto Villegas, described previews of the show as "Crass war propaganda disguised as entertainment". Venezuelan actor Francisco Denis, who plays Ubarri, a senior Venezuelan government official in the new season, responded to his government's criticism by highlighting the fictional character of the series. "I don't think the CIA needs [a show like] this to intervene or not in a country," he said. Denis did regret that the series has included mistakes such as the fictitious meeting of the Venezuelan president with the CIA—which, in his opinion, would never occur under the current administrations—or presenting the most powerful man in the country as "basking in luxury".
 On Rotten Tomatoes, the season holds an approval rating of 67% based on 27 reviews, with an average rating of 6.7 out of 10. The site's critics consensus reads: "Jack Ryan's second season is both more refined and more predictable, doubling down on its espionage set-pieces while toning down its titular character's moral complexities to create a more straight-forward spy show." Metacritic, based upon 6 critics, assigned the season a score of 56 out of 100, indicating "mixed or average reviews".
 
Tim Goodman of The Hollywood Reporter gave a favorable review:  "Jack Ryan is still fun, despite being a little bit ridiculous and predictable ... Not all the events described above make perfect sense and there's definitely some bloat here storytelling-wise, but that never seems to cut into the pacing. It's a strong, appealing cast and an entertaining story — the same successful formula as the first season and a welcome return visitor to the living room". On Rotten Tomatoes, the third season holds an approval rating of 81% based on 21 reviews, with an average rating of 6.6 out of 10. The site's critics consensus reads: "Leaning harder than ever on John Krasinski's earthy charisma, Jack Ryan gets the job done with a third season that doesn't reinvent the formula but executes it with the utmost efficiency." Metacritic, based upon 4 critics, assigned the season a score of 73 out of 100, indicating "generally favorable reviews".
 On Rotten Tomatoes, the fourth season holds an approval rating of 87% based on 15 reviews, with an average rating of 7 out of 10. The site's critics consensus reads: "Reporting in for one final mission, Jack Ryan's fourth season is tasked with delivering brainy thrills and ably gets the job done." Metacritic, based upon 4 critics, assigned the season a score of 73 out of 100, indicating "generally favorable reviews".
